摘要

We reanalyzed the angular distribution data of the 6Li + 58Ni elastic scattering at 6Li energies ranging from 12 to 600 MeV within the optical model framework. Our study pursues three main goals: First, we systematically assess the sensitivity of scattering observables to different double-folding potential configurations. These include the CDM3Y6 effective nucleon-nucleon interaction with a three-body (α+n+p) cluster density of 6Li, as well as the São Paulo (SPP2) and Brazilian (BNP) potentials folded with the Dirac-Hartree-Bogoliubov (DHB) densities of both interacting nuclei, and a phenomenological Woods-Saxon potential of fixed radii. Second, we investigate the energy dependence of the interaction potential through volume integrals and total reaction cross-sections. Third, we quantify the role of channel coupling by performing coupled-channel calculations that include inelastic excitation of both the projectile and target, demonstrating their crucial impact on the elastic scattering description, an effect that is particularly evident in the 600 MeV data.
