Peculiarities of nuclear processes with participation of light ions in the intermediate energy range

The elastic and inelastic differential cross sections of 3He and 4He on atomic nuclei with E > or approximately 100 MeV energy were analysed to determine the real nuclear phase without any model. The diffraction oscillation damping in differential cross sections which was observed experimentally is studied. The oscillationd amping in the differential cross section of the quasielastic charge r eaction (3He, 3H) for the considered energy region is predicted
