Elastic scattering of 318 MeV 6Li from 12C and 28Si: Unique phenomenological and folding-model potentials.

Abstract

The cross sections for elastic scattering of 318 MeV [sup 6]Li from [sup 12]C and [sup 28]Si were measured. The data extend well beyond the rainbow angle into the region where the far-side scattering dominates, and thus define unique [sup 6]Li phenomenological potentials. These complement earlier unique [sup 6]Li potentials derived at an energy of 210 MeV. Double-folded real potentials also were generated using effective nucleon-nucleon interactions. The M3Y and Franey-Love 50 MeV nucleon-nucleon interactions gave similar potentials. A Woods-Saxon form was used for the imaginary potential. The experimental cross-section data were reasonably well reproduced without renormalization of the folded potentials.
