Off-shell effects in multiple scattering of protons on nuclei with A = 3, 4 at 600, 1000 MeV

The Research of multiple center eikonal approach with regard to the scattering of high-energy protons on atomic nuclei is carried out. In contrast to the theory of Glauber-Sitenko, new approach uses three-dimensional generalized profile function of nucleon, which allows taking into account the off-shell effects in intermediate acts of scattering. The formalism that has been developed is applied for the calculations of the cross sections of elastic scattering of protons on 3Н, 3,4Не nuclei at energies of 600 and 1000 MeV. The results of calculations are compared with experimental data and calculations on conventional diffraction theory.
