Abstract
The experimental differential cross-sections for the ⁶Li elastic scattering by ²⁸Si over the incident energies = 7.5– 99.0 MeV and vector analyzing power data at 22.8 MeV have been analyzed in terms of a non-monotonic potential, microscopically derived from the energy-density functional (EDF) theory using a realistic two-nucleon potential that incorporates effects of the Pauli principle. The data are accounted for well without any need for renormalization of the potential or adjustment of its parameters. Inclusion of a static spin-orbit potential with the EDF-generated central real one is found to describe satisfactorily the features of the vector analyzing power data.
