Abstract

The angular distributions of ³²S elastic scattering on²⁸Si has been analyzed at the energies 77.0, 90.0, 97.09, 120.0 and 135.0MeV in the framework of double folding (DF) model. Two semi-microscopic potentials were generated to analyze the elastic scattering: the real cluster potential model for both nuclei is 8α for the ³²S nucleus and ²⁸Si as 7α is constructed, the real of the density independent zero-range M3Y-Raid potential. These two semi-microscopic potentials were compared to those of Woods-Saxon. The imaginary potential part of the three potentials is considered in Woods-Saxon form. Successfully reproduction of the angular distribution cross sections using the three generated potentials is obtained except for the energy 97.09 MeV at backward angles. This disagreement is due to the transfer processes of the α-alpha particle which causes the oscillation curve. The nuclear matter and cluster densities are taken in three Fermi parameters. The energy dependence of the volume integrals and total reaction cross section were also investigated.
