Comparative analysis of proton and pion scattering on the isotopes 6,8Не within Glauber theory

Resumo

The differential cross sections for p^6,8He and p^6,8He scattering at the RIKEN andGSI energies (0.073 and 0.7 GeV per nucleon) were calculated on the basis of Glauber theory. Pion and proton interaction with a nucleus is determined by the multiple-scattering series (Glauber operator), so that various collision multiplicities and their contributions to the summed cross section can be taken into account. The use of the α-n-n wave function for ⁶He and the wave function on the basis of the large-scale shell model (LSSM) for ⁸He makes it possible to calculate analytically scattering matrix elements.
