  • A method for measuring light ion reaction cross-sections

    • An experimental procedure for measuring reaction cross-sections of light ions in the energy range 20 50 MeV/nucleon, using a modified attenuation technique, is described. The detection method incorporates a forward detector that simultaneously measures the reaction cross-sections for five different sizes of the solid angle in steps from 99.1% to 99.8% of the total solid angle. The final reaction cross-section values are obtained by extrapolation to the full solid angle.

  • Energy dependence of proton-nucleus reaction cross sections

  • Tidskriftsartikel (refereegranskat)abstract
    • Reaction cross section data for proton-nucleus scattering up to 1 GeV have been analyzed in a black-disc model. Simple phenomenological relations are derived, which makes it possible to predict the energy depence of proton-nucleus reaction cross sections. The relations require only the total cross sections in nucleon-nucleon scattering and the matter densities of the proton and target nucleus.

    • The reaction cross section gives the probability that a particle will undergo a nonelastic process when passing through a nuclear medium. Therefore reaction cross section data are of importance both for theoretical studies and for applications in such diverse fields as medicine, biology, astrophysics and accelerator-driven transmutation of nuclear waste.There exist many data sets with angular distributions of elastic scattering, but very few measurements of the complementary reaction cross section have been performed. The measurement is in principle simple but has in practice proved to be very difficult to perform, and the relatively limited amount of experimental data displays some serious inconsistencies.Results from measurements of reaction cross sections are presented for:• 3He on 9Be, 12C, 16O, 28Si, 40Ca, 58,60Ni, 112,116,118,120,124Sn and 208Pb at 96, 138 and 167 MeV• protons on 12C, 40Ca, 90Zr and 208Pb at six energies in the energy range 80-180 MeV, and on58Ni at 81 MeV.Experimental uncertainties were 3-9% for 3He and 1.5-8% for protons.The apparatus and the experimental method used for the measurements of reaction cross sections, using a modified attenuation technique, is described. The detection method enables simultaneous measurements of reaction cross sections for five different sizes of the solid angles in steps from 99.0 to 99.8% of the total solid angle. The final results are obtained by extrapolation to the full solid angle.Experimental results are compared with predictions from optical model calculations using phenomenological global optical potentials.Phenomenological parametrizations of reaction cross sections for scattering of projectiles on targets are presented. The parametrizations show that reaction cross sections are very sensitive to matter distributions at very large radii of both the projectile and the target. For protons the derived relations makes it possible to predict the reaction cross sections on targets for which no experimental data exist.
