摘要

Microscopic optical potential of He-4 interaction with nuclei is constructed by means of the single-folding model using the nucleon-nucleus optical potentials, which earlier were successfully applied to describing the neutron and proton scattering and are obtained from approximate calculations of the mass operator of the one-particle Green's function with the effective Skyrme nucleon-nucleon forces. The 4He scattering processes are described in a self-consistent approach based on the standard and extended Skyrme forces, which simultaneously provide a satisfactory description of nuclear structure and nucleon-nucleus scattering. The performed calculations reasonably describe experimental data on differential cross sections of the elastic and inelastic a-particle scattering on different target nuclei in the mass-number range from Si-28 to Pb-208 at different projectile energies below or about 100 MeV, as well as the energy dependences of alpha-particle reaction cross sections on nuclei in a wide energy range.
