Comparative study of alpha scattering from various nuclei at 130 MeV: Microscopic potentials and coupled channel calculations

The angular distributions of the elastic and inelastic scattering cross sections of alpha projectiles on different heavy ion target nuclei, including ¹²C, ¹⁶O, ²⁴Mg, ²⁸Si, and ⁴⁰Ca, at energy of 130 MeV have been studied using two different microscopic real potentials generated by the energy density functional (EDF) theory and single folding cluster model, as well as phenomenological Woods-Saxon potentials. A new parameterization was considered for the first time by EDF, and to make the normalization coefficient tend to unity, it is necessary to consider a correction to the calculated real potential. Coupled channel calculations for various low-lying excited states of the considered targets were performed, and the optimal extracted deformation lengths within the employed models were extracted and compared to previous reported values. The total reaction cross section, as well as the real and imaginary volume integrals, have been studied. (author)
