Microscopic 6Li-28Si potential from the energy-density functional theory

The experimental differential cross-sections for the 6Li elastic scattering by 28Si over the incident energies E(Li) equals 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. (authors)
