Abstract

Real double-folding optical potentials are calculated using the S1Y effective nucleon-nucleon (NN) interaction and the tρρ approximation in order to analyze elastic and inelastic scattering of α-particles from 58Ni, 116Sn, and 208Pb targets at 288, 340, 480, and 699 MeV. The relativistic corrections for momenta and reduced masses are performed to investigate the data at the energies 480 and 699 MeV. The second-order (double-scattering) correction to the tρρ potential is also considered. The inelastic scattering to low-lying excited states (2+) is investigated using the distorted wave born approximation (DWBA) and the coupled-channel (CC) techniques.
