    Measurement of the (n)over-right-arrowp -> d pi(0) pi(0) reaction with polarized beam in the region of the d(*)(2380) resonance2016Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 52, nr 5, s. 1-7, artikkel-id 147Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We report on a high-statistics measurement of the most basic double-pionic fusion reaction over the energy region of the d (*)(2380) resonance by use of a polarized deuteron beam and observing the double fusion reaction in the quasifree scattering mode. The measurements were performed with the WASA detector setup at COSY. The data reveal substantial analyzing powers and confirm conclusions about the d(*) resonance obtained from unpolarized measurements. We also confirm the previous unpolarized data obtained under complementary kinematic conditions.

    Cross section ratio and angular distributions of the reaction p + d -> He-3 + eta at 48.8MeV and 59.8MeV excess energy2014Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 50, nr 6, s. 100-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We present new data for angular distributions and on the cross section ratio of the p+d -> He-3+eta reaction at excess energies of Q - 48.8MeV and Q - 59.8 MeV. The data have been obtained at the WASA-at-COSY experiment (Forschungszentrum Julich) using a proton beam and a deuterium pellet target. While the shape of obtained angular distributions show only a slow variation with the energy, the new results indicate a distinct and unexpected total cross section fluctuation between Q = 20MeV and Q = 60 MeV, which might indicate the variation of the production mechanism within this energy interval.

    Backward single-pion production in the pd -> He-3 pi(0)reaction with WASA-at-COSY2018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, nr 9, artikkel-id 149Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    New data on the production of single neutral pions in the pd -> He-3 pi(0) reaction are presented. For fifteen proton beam momenta between p(p) = 1.60GeV/c and p(p) = 1.74 GeV/c, differential cross sections are determined over a large fraction of the backward hemisphere. Since the only previous systematic measurements of single-pion production at these energies were made in collinear kinematics, the present work constitutes a significant extension of the current knowledge on this reaction. Even this far above the production threshold, significant changes are found in the behaviour of the angular distributions over small intervals in beam momentum.

    Simulations of the fission-product stopping efficiency in IGISOL2015Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 51, nr 59, s. 1-7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    At the Jyväskylä Ion Guide Isotope Separator On-Line (IGISOL) facility, independent fission yields are measured employing the Penning-trap technique. Fission products are produced, e.g. by impinging protons on a uranium target, and are stopped in a gas-filled chamber. The products are collected by a flow of He gas and guided through a mass separator to a Penning trap, where their masses are identified. This work investigates how fission-product properties, such as mass and energy, affect the ion stopping efficiency in the gas cell. The study was performed using the Geant4 toolkit and the SRIM code. The main results show a nearly mass-independent ion stopping with regard to the wide spread of ion masses and energies, with a proper choice of uranium target thickness. Although small variations were observed, in the order of 5%, the results are within the systematic uncertainties of the simulations. To optimize the stopping efficiency while reducing the systematic errors, different experimental parameters were varied; for instance material thicknesses and He gas pressure. Different parameters influence the mass dependence and could alter the mass dependencies in the ion stopping efficiency.

    Extraction of angular momenta from isomeric yield ratios: Employing TALYS to de-excite primary fission fragments2019Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 55, nr 4, artikkel-id 61Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The generation of angular momentum in fission is difficult to model, in particular at higher excitation energies where data are scarce. Isomeric yield ratios (IYR) play an important role in deducing angular momentum properties of fission fragments (FF), albeit this requires some assumptions and simplifications. To estimate FF angular momentum, fission codes can be used to calculate IYRs and compare them to experimental data. Such measurements have systematically been performed at the IGISOL facility using novel experimental techniques. In conjunction, a new method has been developed to infer the angular momentum of the primary FF using the nuclear reaction code TALYS. In this work, we evaluate this new method by comparing our TALYS calculations with values found in the literature and with results from the GEF fission code, for a few well-studied reactions. The overall results show a consistent performance of TALYS and GEF, as well as of many reported literature values. However, some deviations were found, possibly pinpointing the need to re-examine some of the reported literature values. A sensitivity analysis was also performed, in which the role of excitation energy, neutron emission, discrete level structure and level density models were studied. Finally, the role of multiple chance fission, of relevance for the reactions studied at IGISOL, is discussed. Some literature data for this reaction were also re-analyzed using TALYS, revealing significant differences.

    New microsecond isomers in Bi-189,Bi-1902001Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 10, nr 2, s. 129-133Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    New microsecond isomers in the neutron-deficient isotopes Bi-189g,Bi-190 have been identified after in-flight separation by the velocity filter SHIP. The evaporation residues were identified on the basis of delayed recoil-gamma /X-ray, recoil-gamma /X-ray-alpha and excitation function measurements. The systematics of the [pi 1i(13/2)]13/2(+) excited states in the odd-mass Bi nuclei is discussed.

    The Giant Pairing Vibration in heavy nuclei Present status and future studies2019Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 55, nr 12, artikkel-id 245Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Giant Pairing Vibration, a two-nucleon collective mode originating from the second shell above the Fermi surface, has long been predicted and expected to be strongly populated in two-nucleon transfer reactions with cross sections similar to those of the low-lying Pairing Vibration. Recent experiments have provided evidence for this mode in C-14,C- 15 but, despite sensitive studies, it has not been definitively identified in Sn or Pb nuclei where pairing correlations are known to play a crucial role near their ground states. In this paper we review the basic theoretical concepts of this "elusive" state and the status of experimental searches in heavy nuclei. We discuss the hindrance effects due to Q-value mismatch and the use of weakly-bound projectiles as a way to overcome the limitations of the (p,t) reactions. We also discuss the role of the continuum and conclude with some possible future developments.

    Neutron correlations in 6He viewed through nuclear break-up2009Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 42, nr 3, s. 441-446Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The nuclear break-up of He-6 on a Pb-208 target was studied at 20 A MeV using a secondary beam of He-6 produced by the SPIRAL facility at GANIL. alpha-particles were detected in coincidence with two neutrons with a large angular coverage and the reaction mechanism was identified. From the distribution of the relative angles between the two neutrons the correlation function was extracted. It shows a strong correlation at small relative angles attributed to the contribution of the di-neutron configuration of He-6.

    Excited superdeformed band in Eu-1431999Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 6, nr 2, s. 175-183Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A new superdeformed band has been discovered in a EUROBALL experiment and assigned to Eu-143. It has a maximum intensity of 35% of the Eu-143 yrast superdeformed band and the transition energies of the two bands are very similar. Based on comparison with cranked shell model calculations the new band is tentatively assigned the high-N intruder configuration pi 6(2)nu 7(0) and the parity and signature quantum numbers (pi, alpha) = (-1, +1/2). In addition to the already known high-energy transition at 3361 keV another discrete line at 2715 keV was found to be in coincidence with the yrast superdeformed band. However, it was not possible to connect the decay out of either of the superdeformed bands to, known normally deformed states.

    Precision resonance energy scans with the PANDA experiment at FAIR: Sensitivity study for width and line shape measurements of the X(3872)2019Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 55, nr 3, artikkel-id 42Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    .This paper summarises a comprehensive Monte Carlo simulation study for precision resonance energy scan measurements. Apart from the proof of principle for natural width and line shape measurements of very narrow resonances with PANDA, the achievable sensitivities are quantified for the concrete example of the charmonium-like X(3872) state discussed to be exotic, and for a larger parameter space of various assumed signal cross-sections, input widths and luminosity combinations. PANDA is the only experiment that will be able to perform precision resonance energy scans of such narrow states with quantum numbers of spin and parities that differ from JPC=1--.

    Feasibility of low-energy radiative-capture experiments at the LUNA underground accelerator facility2005Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 24, nr 2, s. 313-319Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The LUNA (Laboratory Underground for Nuclear Astrophysics) facility has been designed to study nuclear reactions of astrophysical interest. It is located deep underground in the Gran Sasso National Laboratory, Italy. Two electrostatic accelerators, with 50 and 400 kV maximum voltage, in combination with solid and gas target setups allowed to measure the total cross-sections of the radiative-capture reactions 2H2H(p, γ) 3He3Heand 14N14N(p, γ) 15O15Owithin their relevant Gamow peaks. We report on the gamma background in the Gran Sasso laboratory measured by germanium and bismuth germanate detectors, with and without an incident proton beam. A method to localize the sources of beam-induced background using the Doppler shift of emitted gamma rays is presented. The feasibility of radiative-capture studies at energies of astrophysical interest is discussed for several experimental scenarios. © Società Italiana di Fisica/Springer-Verlag 2005.

    Cluster emission from superheavy nuclei2018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, nr 11, artikkel-id 200Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The process leading to cluster emission from superheavy nuclei in the range 100 122 has been systematically investigated. This topic is of importance because it opens up the possibility of identifying superheavy elements through deposition of clusters in the detection system. In this paper we evaluate the cluster decay half lives by considering the cluster as a particle. The motion of this particle in the field induced by the daughter nucleus is determined by solving the corresponding Schrodinger equation imposing outgoing boundary conditions (Gamow state). The corresponding Wood-Saxon potential is fitted to obtain the energies provided by a mass formula that has been established recently to have a very high degree of precision. The resulting expression for the decay width is exact, i.e. no approximation besides the assumption of a preformed cluster is introduced. It is found that the heavy cluster emission probability in the superheavy region is much smaller than the corresponding a emission probability.

    Spectroscopy of the neutron-deficient nuclide Pt-1712003Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 17, nr 1, s. 1-5Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A number of previously unobserved gamma-rays emitted from the neutron-deficient nuclide Pt-171 have been identified using the recoil decay tagging technique. The level scheme has been updated using information from gamma-gamma coincidences and angular distribution measurements. To further confirm the assignments of the gamma-rays to Pt-171, the events were correlated with the alpha-decay of the daughter nucleus Os-167.

    First observation of gamma-rays from the proton emitter Au-1712003Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 16, nr 4, s. 489-494Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Gamma-rays from the alpha- and proton-unstable nuclide Au-171 have been observed for the first time. The gamma-rays were correlated with both a proton- and an alpha-particle decay branch, confirming that the nucleus decays by alpha and proton emission from a single (11/2(-)) state. The measurement confirms the previously determined half-lives for these particle decays but the present values are of higher precision. In addition, a longer half-life than determined in previous work was measured for the proton-unstable tentative ground state. The results are discussed in relation to structures in neighbouring nuclei and compared with a Strutinsky-type TRS calculation.

    Observation of superdeformed states in Mo-881999Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 6, nr 4, s. 391-397Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    High-spin states in Mo-88 were studied using the GAMMASPHERE germanium detector array in conjunction with the MICROBALL CsI(TI) charged-particle detector system. Three gamma-ray cascades with dynamic moments of inertia showing similar characteristics to superdeformed rotational bands observed in the neighbouring A = 80 region have been identified and assigned to the nucleus Mo-88. The quadrupole moment of the strongest band, deduced by the Residual Doppler Shift Method, corresponds to a quadrupole deformation of beta(2) approximate to 0.6. This confirms the superdeformed nature of this band. The experimental data are interpreted in the framework of total routhian surface calculations. All three hands are assigned to two-quasi-particle proton configurations at superdeformed shape.

    Favoured superdeformed states in 89TC1999Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 6, nr 3, s. 251-255Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A superdeformed band consisting of a cascade of ten gamma-ray transitions has been identified and assigned to the nucleus Tc-89, close to the proton dripline. The quadrupole moment of the band (Q(t) = 6.7(-2.3)(+3.0) eb, as measured by the Residual Doppler Shift Method) as well as a large dynamic moment of inertia point to a highly elongated shape. With a relative population of approximately 15% of the gamma-ray flux in the Tc-89 exit channel, thp band is among the most intense superdeformed bands observed to date.

    Feasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR2016Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 52, nr 10, artikkel-id 325Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Simulation results for future measurements of electromagnetic proton form factors at P ¯ ANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel p¯ p→ e+e- is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e.p¯ p→ π+π-, is studied. Furthermore, the background versus signal efficiency, statistical and systematical uncertainties on the extracted proton form factors are evaluated using two different procedures. The results are consistent with those of a previous simulation study using an older, simplified framework. However, a slightly better precision is achieved in the PandaRoot study in a large range of momentum transfer, assuming the nominal beam conditions and detector performance.

    The fission experimental programme at the CERN n_TOF facility: status and perspectives2020Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 56, nr 2Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Neutron-induced fission reactions play a crucial role in a variety of fields of fundamental and applied nuclear science. In basic nuclear physics they provide important information on properties of nuclear matter, while in nuclear technology they are at the basis of present and future reactor designs. Finally, there is a renewed interest in fission reactions in nuclear astrophysics due to the multi-messenger observation of neutron star mergers and the important role played by fission recycling in r-process nucleosynthesis. Although studied for several decades, many fundamental questions still remain on fission reactions, while modern applications and the development of more reliable nuclear models require high-accuracy and consistent experimental data on fission cross sections and other fission observables. To address these needs, an extensive fission research programme has been carried out at the n_TOF neutron time-of-flight facility at CERN during the last 18 years, taking advantage of the high energy resolution, high luminosity and wide energy range of the neutron beam, as well as of the detection and data acquisition systems designed for this purpose. While long-lived isotopes are studied on the 185 m long flight-path, the recent construction of a second experimental area at a distance of about 19 m has opened the way to challenging measurements of short-lived actinides. This article provides an overview of the n_TOF experimental programme on neutron-induced fission reactions along with the main characteristics of the facility, the various detection systems and data analysis techniques used. The most important results on several major and minor actinides obtained so far and the future perspectives of fission measurements at n_TOF are presented and discussed.

    Electromagnetic properties of vibrational bands in Er-1702011Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 47, nr 2, s. 25-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Excited states of the nucleus Er-170 have been studied by Coulomb excitation using the GASP gamma-ray detector system at the Laboratori Nazionali di Legnaro. The ground-state band along with a low-lying K-pi = 0(+) band and gamma-vibrational band were populated during the experiment. Based on the measured gamma-ray yields, a set of interband and intraband matrix elements has been extracted using the Coulomb excitation code GOSIA. The resulting E2 matrix elements are compared to collective model predictions.

    Determination of lifetimes of nuclear excited states using the Recoil Distance Doppler Shift Method in combination with magnetic spectrometers2017Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 53, nr 10, artikkel-id 211Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The current work presents the determination of lifetimes of nuclear excited states using the Recoil Distance Doppler Shift Method, in combination with spectrometers for ion identification, normalizing the intensity of the peaks by the ions detected in the spectrometer as a valid technique that produces results comparable to the ones obtained by the conventional shifted-to-unsifted peak ratio method. The technique has been validated using data measured with the gamma-ray array AGATA, the PRISMA spectrometer and the Cologne plunger setup. In this paper a test performed with the AGATA-PRISMA setup at LNL and the advantages of this new approach with respect to the conventional Recoil Distance Doppler Shift Method are discussed.

    M1 And E2 Transition Rates From Core-Excited States In Semi-Magic Ru-942018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, nr 9, artikkel-id 145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Lifetimes of high-spin states have been measured in the semi-magic (N = 50) nucleus Ru-94. Excited states in Ru-94 were populated in the Ni-58(Ca-40, 4p)Ru-94* fusion-evaporation reaction at the Grand Accelerateur National d'Ions Lourds (GANIL) accelerator complex. DSAM lifetime analysis was performed on the Doppler broadened line shapes in energy spectra obtained from gamma-rays emitted while the residual nuclei were slowing down in a thick 6 mg/cm(2) metallic Ni-58 target. In total eight excited-state lifetimes in the angular momentum range I = (13-20)h have been measured, five of which were determined for the first time. The corresponding B(M1) and B(E2) reduced transition strengths are discussed within the framework of large-scale shell model calculations to study the contribution of different particle-hole configurations, in particular for analyzing contributions from core-excited configurations.

    Evidence for octupole collectivity in Pt-1722020Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 56, nr 2, artikkel-id 65Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Excited states in the extremely neutron-deficient nucleus Pt-172 were populated via Ru-96(Kr-78, 2p) and Mo-92(Kr-83, 3n) reactions. The level scheme has been extended up to an excitation energy of approximate to 5MeV and tentative spin-parity assignments up to I-pi = 18(+). Linear polarization and angular distribution measurements were used to determine the electromagnetic E1 character of the dipole transitions connecting the positive-parity ground-state band with an excited side-band, firmly establishing it as a negativeparity band. The lowestmember of this negative-parity structure was firmly assigned spin-parity 3(-). In addition, we observed an E3 transition from this 3(-) state to the ground state, providing direct evidence for octupole collectivity in Pt-172. Large-scale shell model (LSSM) and total Routhian surface (TRS) calculations have been performed, supporting the interpretation of the 3(-) state as a collective octupole-vibrational state.

    Entanglement in joint Lambda(Lambda)over-bar decay2015Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 51, nr 7, artikkel-id 74Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigate the joint decay in the reaction . This reaction may provide information on the electromagnetic form factors of the Lambda baryon, in the time-like region. We present a conventional diagram-based calculation where production and decay steps are coherent and summations over final-state proton and anti-proton spins are performed. The resulting cross-section distribution is explicitly covariant as it is expressed in scalar products of the four-momentum vectors of the participating particles. We compare this calculation with that of the folding method which we extend and make explicitly covariant. In the folding method production and decay distributions, not amplitudes, are folded together. Of particular importance is then a correct counting of the number of possible intermediate-hyperon-spin states.

    Polarization observables in the e+e- ->(Lambda)over-bar Lambda reaction2016Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 52, nr 5, artikkel-id 141Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cross-section, vector-polarization, and tensor-polarization distributions are calculated for the reactions e(+)e(-) -> (p) over barp and e(+)e(-) ->(Lambda) over bar Lambda . Each reaction requires six characteristic functions that are bilinear in the, possibly complex, electromagnetic Form factors, denoted G(E)(P-2) and G(M) (P-2), of p and A. For the hyperon reaction also the joint-decay distributions of A and A are calculated. Their knowledge allows a complete determination of the hyperon electromagnetic form factors, without measuring hyperon spins. We explain how this is done in practice. For some tensor-polarization components our results are in conflict with previously repeatedly published distributions.

    Cranking in isospace2004Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 19, nr 1, s. 33-44Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The response of isovector and isoscalar pair fields to generalized rotation in isospace is studied. Analytical expressions for constant gap solutions for different limiting cases of the model are derived. In particular, the connections between gauge angles among pairing gaps and the position of the iso-cranking axis are investigated in N = Z nuclei. The two domains of collective and noncollective rotation in space are generalized to isospace. The amplitudes for pair-transfer of T = 0 and T = 1 pairs are calculated. It is shown that the structure of the T = 0 state in odd-odd nuclei prevents any enhancement of pair transfer also in the presence of strong isoscalar pairing correlations. The energy differences of the T = 0 and T = 1 excitations in odd-odd nuclei are qualitatively reproduced by Total-Routhian-Surface calculations.

    Systematics of high-spin isomers in N=83 isotones and a high-spin isomer beam2002Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 13, nr 02-jan, s. 5-8Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Isomers in N = 83 isotones of Z = 60 66 were studied systematically. Their spins and parities arc,49/2(+) and 27(+) for odd and odd-odd nuclei, respectively. Nearly constant excitation energies of these isomers indicated a decrease of a Z = 64 shell gap energy as Z decreases from 64 to 60 within the framework of a deformed independent-particle model (DIPM). Their configurations are [v(f(tau/2)h(9/2)i(13/2)), pi(h(11/2))(2)](49/2+) and [v(f(7/2)h(9/2)i(13/2)), pi(h(11/2))(2)(d(5/2))(-1)](27+) for odd and odd-odd nuclei, respectively. The shape of the yrast status changes suddenly at spin 49/2(odd) and 27(odd-odd) from a near spherical to an oblate shape. Transitions from isomers are highly hindered because of the shape changes. They may be categorized to be shape isomers. The development of a secondary beam produced by using these high-spin isomers is also described.

    The electromagnetic Sigma-to-Lambda hyperon transition form factors at low energies2017Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 53, nr 6, artikkel-id 117Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Using dispersion theory the low-energy electromagnetic form factors for the transition of a Sigma to a Lambda hyperon are related to the pion vector form factor. The additionally required input, i.e. the two-pion-Sigma-Lambda amplitudes are determined from relativistic next-to-leading-order (NLO) baryon chiral perturbation theory including the baryons from the octet and optionally from the decuplet. Pion rescattering is again taken into account by dispersion theory. It turns out that the inclusion of decuplet baryons is not an option but a necessity to obtain reasonable results. The electric transition form factor remains very small in the whole low-energy region. The magnetic transition form factor depends strongly on one not very well determined low-energy constant of the NLO Lagrangian. One obtains reasonable predictive power if this low-energy constant is determined from a measurement of the magnetic transition radius. Such a measurement can be performed at the future Facility for Antiproton and Ion Research (FAIR).

    The relativistic chiral Lagrangian for decuplet and octet baryons at next-to-leading order2018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, nr 6, artikkel-id 103Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A complete and minimal relativistic Lagrangian is constructed at next-to-leading order for SU(3) chiral perturbation theory in the presence of baryon octet and baryon decuplet states. The Lagrangian has 13 terms for the pure decuplet sector, 6 terms for the transition sector from baryon octet to decuplet and (as already known from the literature) 16 terms for the pure octet sector. The minimal field content of 25 of these terms is meson-baryon four-point interactions. 3 terms give rise to the mass splitting for baryon octet and decuplet states, respectively. 2 terms give rise to overall mass shifts. 4 terms provide anomalous magnetic moments and a decuplet-to-octet magnetic transition moment. 1 term leads to an axial vector transition moment. It is shown that meson-baryon three-point coupling constants come in at leading order whereas no additional one appears in the minimal Lagrangian at next-to-leading order. Those low-energy constants that give rise to mass splitting and magnetic moments, respectively, are determined. Predictions are provided for radiative decays of decuplet to octet baryons.

    Conceptual design of the early implementation of the NEutron Detector Array (NEDA) with AGATA2016Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 52, nr 3, artikkel-id 55Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The NEutron Detector Array (NEDA) project aims at the construction of a new high-efficiency compact neutron detector array to be coupled with large gamma-ray arrays such as AGATA. The application of NEDA ranges from its use as selective neutron multiplicity filter for fusion-evaporation reaction to a large solid angle neutron tagging device. In the present work, possible configurations for the NEDA coupled with the Neutron Wall for the early implementation with AGATA has been simulated, using Monte Carlo techniques, in order to evaluate their performance figures. The goal of this early NEDA implementation is to improve, with respect to previous instruments, efficiency and capability to select multiplicity for fusion-evaporation reaction channels in which 1, 2 or 3 neutrons are emitted. Each NEDA detector unit has the shape of a regular hexagonal prism with a volume of about 3.23 l and it is filled with the EJ301 liquid scintillator, that presents good neutron-gamma discrimination properties. The simulations have been performed using a fusion-evaporation event generator that has been validated with a set of experimental data obtained in the Ni-58 + Fe-56 reaction measured with the Neutron Wall detector array.

    Abstract [en]

    An in-beam gamma-ray spectroscopy study, following a fusion reaction induced by a neutronrich secondary beam, Ar-46 + Be-9, is presented. A low-energy secondary beam of Ar-46 at similar to 5 MeV/A was developed in order to induce fusion reactions. Gamma-gamma coincidence and excitation function analysis was performed to study high-spin states in the vicinity of Ca-48, Ti49-52.

    S-factor of 14N(p,γ)15O at astrophysical energies2005Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 25, nr 3, s. 455-466Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The astrophysical S(E) factor of 14N(p,γ)15O has been measured for effective center-of-mass energies between E eff = 119 and 367 keV at the LUNA facility using TiN solid targets and Ge detectors. The data are in good agreement with previous and recent work at overlapping energies. R-matrix analysis reveals that due to the complex level structure of 15O the extrapolated S(0) value is model dependent and calls for additional experimental efforts to reduce the present uncertainty in S(0) to a level of a few percent as required by astrophysical calculations. © Società Italiana di Fisica / Springer-Verlag 2005.

    The impact of neutron emission on correlated fission data from the 2E-2v method2018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, artikkel-id 114Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The double-energy double-velocity (2E-2v) method allows assessing fission-fragment mass yields prior to and after prompt neutron emission with high resolution. It is, therefore, considered as a complementary technique to assess average prompt neutron multiplicity as a function of fragment properties. We have studied the intrinsic features of the 2E-2v method by means of event-wise generated fission-fragment data and found short-comings in the method itself as well as in some common practices of application. We find that the 2E-2v method leads to large deviations in the correlation between the prompt neutron multiplicity and pre-neutron mass, which deforms and exaggerates the so-called “sawtooth” shape of nubar(A). We have identified the treatment of prompt neutron emission from the fragments as the origin of the problem. The intrinsic nature of this deficiency risks to render 2E-2v experiments less interesting. We suggest a method to correct 2E-2v data that can even be applied on existing measurements.

    Simulated production rates of exotic nuclei from the ion guide for neutron-induced fission at IGISOL2017Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 53, nr 12, artikkel-id 243Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    An investigation of the stopping efficiency of fission products, in the new ion guide designed for ion production through neutron-induced fission at IGISOL in Jyväskylä, Finland, has been conducted. Our simulations take into account the new neutron converter, enabling measurements of neutron-induced fission yields, and thereby provide estimates of the obtained yields as a function of primary proton beam current. Different geometries, targets, and pressures, as well as models for the effective charge of the stopped ions were tested, and optimisations to the setup for higher yields are suggested. The predicted number of ions stopped in the gas lets us estimate the survival probability of the ions reaching the downstream measurements stations.

    Nuclear structure in the vicinity of the N = Z line in the A=90-100 region2002Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 13, nr 02-jan, s. 9-14Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neutron-deficient nuclei in the mass region A approximate to 90-100 exhibit a large variety of phenomena. In this region the heaviest N = Z nuclei are identified and enhanced neutron-proton correlations are expected when protons and neutrons occupy identical orbitals. A variety of nuclear shapes are predicted and observed for A less than or equal to 91, including superdeformed shapes. The nucleus Sn-100 is the heaviest N = Z doubly magic nucleus believed to be bound. Knowledge of the shell structure around 100Sn is of utmost importance for understanding the nuclear shell model. New results on both the N = Z nucleus Ru-88, superdeformed structures in A approximate to 90 nuclei as well as the first result on the level structure in Sn-103, and an extended level structure in In-102 are presented. The limitations of using stable beams and targets and the possibilities with new radioactive beams are briefly outlined.

    Determination of the Ir-193(n, 2n) reaction cross section and correction methodology for the Ir-191(n, gamma) contamination2019Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 55, nr 10, artikkel-id 187Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The cross section of the Ir-193(n, 2n)Ir-192 reaction has been determined by means of the activation technique, relative to the Al-27(n, alpha) and Au-197(n, 2n) reference reactions cross sections, at neutron beam energies ranging from 10 to 21 MeV. The quasi-monoenergetic neutron beams were produced at the 5.5 MV Tandem T11/25 Accelerator Laboratory of NCSR "Demokritos" via the H-2(d, n) and H-3(d, n) reactions. The induced gamma-ray activity of the irradiated target and reference foils was measured with high resolution HPGe detectors. In order to correct for the contribution of the Ir-191(n, gamma)Ir-192 reaction, which is open to low energy parasitic neutrons, a recently developed analysis method was implemented and it is presented in great detail. Furthermore, cross section theoretical calculations were carried out using the EMPIRE and TALYS codes over a wide energy range.

    On the unusual properties of the 282 keV state in 135Sb2007Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 32, nr 1, s. 25-29Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recently the first excited state in 135Sb has been observed at the unexpectedly low excitation energy of only 282keV and interpreted as mainly d 5/2 proton coupled to the 134Sn core. Based on theoretical considerations it was suggested that its low excitation energy is related to a relative shift of the proton d 5/2 and g 7/2 orbits induced by the neutron excess. We have measured the lifetime of the 282keV state by the advanced time-delayed βγγ(t) method. The measured half-life, T 1/2 = 6.1(4)ns, yields exceptionally low limits of B(M1;5/21 +→7/21 +)≤3.0×10-4 μ 2 N and B(E2;5/21 +→7/21 +)≤54e 2 fm 4. These strongly hindered M1 and slow E2 transition rates are similar to those for the transition de-populating the first excited state at 405keV in 211Bi. Results of shell model calculations with realistic interactions are presented. The M1 decay rate was found to be extremely sensistive both to the wave function and to the M1 effective operator.

    Evidence for excited states in Ag-952002Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 14, nr 4, s. 393-396Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The first evidence for excited states in Ag-95 is presented. Ag-95 is the heaviest T-z = 1/2 nucleus for which gamma-rays have been identified. The reaction Ca-40(Ni-58, 1p2n)Ag-95 was used in the experiment, which resulted in the assignment of three gamma-rays to Ag-95. A detector system consisting of the detector arrays Euroball, Neutron Wall and Euclides was used to detect gamma-rays, neutrons and charged particles, respectively.

    Experimental evidence for tunneling in the decay of superdeformed states2004Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 21, nr 2, s. 175-177Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A systematic study of the depopulation of superdeformed rotational bands in neutron-deficient A approximate to 80-90 nuclei has been performed. We observed a correlation between the rotational frequency at which the decay out of the superdeformed bands takes place and the difference between the transition quadrupole moments of states in the superdeformed bands and high-lying states with normal deformation. The observation may constitute direct experimental evidence that the commonly adopted tunneling picture for the decay of superdeformed states is valid.

    Isospectral superdeformed bands in the N=46 nuclei Mo-88 and Tc-892004Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 21, nr 3, s. 375-381Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Superdeformed bands in Mo-88 and Tc-89 were populated Using Ca-40-induced fusion-evaporation reactions on Ni-58 at a beam energy of 185 MeV. Gamma-rays emitted in the reactions were detected using the Gammasphere spectrometer, in coincidence with charged particles detected by the Microball array. A new superdeformed band was assigned to the nucleus Mo-88, leading to a revisit of earlier configuration assignments for superdeformed structures in this nucleus. In particular, the theoretical interpretation of a pair of identical (isospectral) superdeformed bands in Mo-88/Tc-89 is discussed. The configurations that are assigned to the four SD bands belonging to Mo-88 have properties that are predicted to be significantly affected by pair correlations.

    The nucleon as a test case to calculate vector-isovector form factors at low energies2018Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 54, nr 1, artikkel-id 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Extending a recent suggestion for hyperon form factors to the nucleon case, dispersion theory is used to relate the low-energy vector-isovector form factors of the nucleon to the pion vector form factor. The additionally required input, i.e. the pion-nucleon scattering amplitudes are determined from relativistic next-to-leading-order (NLO) baryon chiral perturbation theory including the nucleons and optionally the Delta baryons. Two methods to include pion rescattering are compared: a) solving the Muskhelishvili-OmnSs (MO) equation and b) using an N/D approach. It turns out that the results differ strongly from each other. Furthermore the results are compared to a fully dispersive calculation of the (subthreshold) pion-nucleon amplitudes based on Roy-Steiner (RS) equations. In full agreement with the findings from the hyperon sector it turns out that the inclusion of Delta baryons is not an option but a necessity to obtain reasonable results. The magnetic isovector form factor depends strongly on a low-energy constant of the NLO Lagrangian. If it is adjusted such that the corresponding magnetic radius is reproduced, then the results for the corresponding pion-nucleon scattering amplitude (based on the MO equation) agree very well with the RS results. Also in the electric sector the Delta degrees of freedom are needed to obtain the correct order of magnitude for the isovector charge and the corresponding electric radius. Yet quantitative agreement is not achieved. If the subtraction constant that appears in the solution of the MO equation is not taken from nucleon+Delta chiral perturbation theory but adjusted such that the electric radius is reproduced, then one obtains also in this sector a pion-nucleon scattering amplitude that agrees well with the RS results.

    Reinvestigation of the collective band structures in odd-odd Pm-138 nucleus2015Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 51, nr 5, artikkel-id 60Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The high-spin states in the odd-odd Pm-138 nucleus have been reinvestigated via the Te-124(F-19, 5n) reaction at the beam energy of 103MeV. Most of the known transitions and levels are confirmed. A number of bands are revised and one new band has been established. For the yrast pi h(11/2) circle times nu h(11/2) band based on 8(+) state, no evidence supporting the occurence of signature inversion is found. The experimental and theoretical B(M1)/B(E2) ratios have been calculated for band (2), which support the pi g(7/2)[413]5/2(+) circle times nu h(11/2)[514]9/2(-) Nilsson configuration assignment. Four bands with Delta I = 2 transitions are tentatively assigned as doubly decoupled bands. The other three bands are proposed as oblate-triaxial bands. The possible configuration assignments for these bands are also discussed under the calculations of total Routhian surface and particle-rotor model.

    Investigations of the level scheme of Gd-144 and lifetimes in the quadrupole bands2004Inngår i: European Physical Journal A, ISSN 1434-6001, E-ISSN 1434-601X, Vol. 21, nr 1, s. 37-55Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For a level scheme investigation of Gd-144 an experiment with the gamma-spectrometer EUROBALL III has been carried out and lifetimes have been measured with the gamma-spectrometer GASP using the Doppler-shift attenuation method. The high-spin states have been populated in these experiments by means of the Mo-100(Ti-48,4n) reaction at 215 MeV and the Cd-114(S-36,6n) reaction at E = 182 MeV, respectively. The known quadrupole band has been modified and a new one has been established. Reduced E2 transition probabilities B(E2) were determined for seven members of these quadrupole bands. They show values between approximate to60 and 130 W.u. and this considerable enhancement gives evidence for a significant nuclear deformation. A (pih(11/2))(2) circle times (vh(11/2))(-2) configuration may be assigned to one of the quadrupole bands according to total Routhian surface calculations. The spin dependence of the B(E2) values has been explained by IBM calculations involving high-spin quasiparticle excitations.
