  Within the framework of the Glauber diffraction theory, the differential
cross sections of the elastic p6He, p8Li, and p9Li scattering were calculated
at intermediate energies from 70 to 1000 MeV/nucleon. The use of realistic
three-body wave functions alpha-n-n (6He), alpha-t-n (8Li) and alpha-t-2n
(9Li), obtained in the framework of modern clear models, and the expansion of
the Glauber operator into a series of multiple scatterings in a form that is
well adapted to the three-body nuclei configuration, allows the calculation of
the matrix elements, by taking into account the rescattering from all structure
components of the designated nuclei.
