    Pi0 and eta spectra from proton-antiproton annihilations at rest1984In: Zeitschrift für Physik. C, Particles and fields, ISSN 0170-9739, Vol. 21, no 4, p. 315-319Article in journal (Refereed)
    Abstract [en]

    The low-energy part of the π0 spectrum associated with Mathematical expression annihilation at rest was measured in order to search for bound baryonium-like states. The upper limit for reaching such states via the emission of monochromatic π0’s was found to be 8% per annihilation in the mass region of 1650 MeV. The low-energy part of the η spectrum from Mathematical expression annihilations at rest was also observed.

    Search for narrow signals in the [gamma]-spectrum from [Proton-antiproton] annihilation at rest1986In: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 182, no 3-4, p. 405-408Article in journal (Refereed)
    Abstract [en]

    The [gamma]-spectrum originating from pp[combining macron] annihilations at rest in liquid hydrogen was measured with two BGO spectrometers. A total of 24 ï¿œ 106[gamma]’s were accumulated. No narrow peaks indicating exotic states such as baryonium were observed. The upper limit for the branching ratio with 1040 [less-than-or-equals, slant] mx [less-than-or-equals, slant] 1770 MeV/c2 and with [lambda]x [less-than-or-equals, slant] 25 MeV/c2 is less than 10-3 with more than 99.96% confidence.

    Search for narrow exotic states in annihilations on 4He1984In: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 138, no 1-3, p. 235-240Article in journal (Refereed)
    Abstract [en]

    After having found evidence for narrow exotic states in p annihilation, the production of such states on a nuclear target was studied with similar techniques. The γ spectrum associated with annihilation on 4He at rest was measured. The spectrum shows two peaks, at energies of 161.9 and 203.0 MeV, corresponding to intermediate narrow states of masses which seem to be related to states found in p annihilations. The confidence is better than 4 σ.

    Progress in mathematics during earlier years in Swedish school2009Conference paper (Other academic)
    Abstract [en]

    Abstract: The results of the improvement in Math between school year 3-4, 5-6-7 and 8-9 in the Swedish school system is analysed using the effect-size estimator. The result shows that the yearly improvement decreases in particular when the pupils reach school year 7-9. The estimate is based on the Swedish version of the international kangaroo competition. A few points on reliability are discussed. The validity of using this particular data is also discussed.

    Where did Technology Go?2009In: Strengthening the Position of Technology Education in the Curriculum / [ed] Arien Becker, Ilja Mottier, Marc J. de Vries, Delft: Delft University of Technology , 2009, p. 1-5Conference paper (Refereed)
    Abstract [en]

    In the beginning there was techne and episteme. Today we have difficulties with finding technology in the implementations of the curriculum in, at least, Swedish schools. So where did it go? I will give arguments that it is all there but it suffers from specialisation. If we think of techne appearing before the different natural science subjects it is a very natural thought that technology today is what is left "between" the more specialized subjects. However I believe that technology is created also in the meeting between two specialized subjects. When a physicist work with a chemist to solve a problem, than this work will very easy appear as technology from one or both parts view. Also not a revolutionary thought this may explain why the Swedish higher education is organized as it is and why we have diffculties to make a working curriculum for the lower grades.

    Abstract [en]

    The γ-ray spectrum after p annihilation at rest was measured in two independent high-statistics runs. Both spectra show narrow peaks, corresponding to masses of 1210, 1638, 1694 and 1771 MeV.
