Rescattering effects in proton scattering on nuclei 6,8He and 8,9Li in the Glauber theory

Abstract

The differential cross sections of elastic p6,8He and p8,9Li scattering are calculated within the Glauber diffraction theory at intermediate energies of 70 to 700 MeV/nucleon. The calculations are based on realistic three-body wave functions α-n-n (for 6He), α-2n-2n (for 8He), α-t-n (for 8Li), α-t-2n (for 9Li), obtained using current nuclear models, and the Glauber operator is expanded into a series of multiple scattering corresponding to the three-body nuclei configuration. The approach allows us to calculate the operator matrix elements with allowance for rescattering on all structural components of the investigated nuclei.
