Comparative analysis of proton and pion scattering on the isotopes 68He within Glauber Theory

The differential cross sections for p[sup.6,8]He and [pi][sup.6,8]He scattering at the RIKEN and GSI 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 [alpha] - n - n wave function for [sup.6]He and the wave function on the basis of the large-scale shell model (LSSM) for [sup.8]He makes it possible to calculate analytically scattering matrix elements.
