Abstract
The differential cross sections of elastic p 6,8 He and p 8,9 Li 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 6 He), α-2n-2n (for 8 He), α-t-n (for 8 Li), α-t-2n (for 9 Li), 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.
