Energy dependence of the optical potential for 16O + 28Si, elastic scattering in the energy range of E = 55–215 MeV

Abstract

The energy dependence of an optical potential which reasonably fits all of the existing experimental data on 16O + 28Si elastic scattering in the energy range of E = 54.7–215.2 MeV is studied. The real part of the potential found for this system shows a transition from a proximity to a double-folding type of the potential as a result of quenching of the Pauli principle effects with an increase of the incident energy. The imaginary part shows a transition from a surface-transparent to a strongly absorptive type of the potential.
