Elastic scattering and total reaction cross sections for the 8B, 7Be, and 6Li +12C systems

摘要

Angular distributions for the elastic scattering of 8B, 7Be, and 6Li on a 12C target have been measured at Elab=25.8, 18.8, and 12.3 MeV, respectively. The analyses of these angular distributions have been performed in terms of the optical model using Woods-Saxon and double-folding type potentials. The effect of breakup in the elastic scattering of 8B+12C is investigated by performing coupled-channels calculations with the continuum discretized coupled-channel method and cluster-model folding potentials. Total reaction cross sections were deduced from the elastic-scattering analysis and compared with published data on elastic scattering of other weakly and tightly bound projectiles on 12C, as a function of energy. With the exception of 4He and 16O, the data can be described using a universal function for the reduced cross sections.
