Contribution of Higher Multiplicity Collisions to Elastic p(6,8)He and p(8,9)Li Scattering within Glauber Theory

摘要

Differential cross sections for elastic p(6,8)He and p(8,9)Li scattering at energies between 60 and 70 MeV per nucleon and at the energy of 700 MeV per nucleon were calculated. The calculations in question were performed with the wave functions found on the basis of the alpha-n-n (for He-6), alpha-t-n (for Li-8), and alpha-t-2n (for Li-9) three-body models and with the density from the large-scale shell model for the He-8 nucleus. The respective matrix elements were derived either upon taking fully into account the multiple-scattering operator or in the optical-limit approximation. A comparison of the results of the precise and approximate calculations made it possible to estimate reliably the contribution of higher multiplicity collisions to the differential cross sections.
