Abstract

We present new experimental angular distributions for the elastic scattering of Li-6 + Sn-120 at three bombarding energies. We include these data in a wide systematic involving the elastic scattering of He-4,He-6,Li- 7, Be-9, B-10, and O-16,O-18 projectiles on the same target at energies around the respective Coulomb barriers. Considering this data set, we report on optical model analyses based on the double-folding Sao Paulo potential. Within this approach, we study the sensitivity of the data fit to different models for the nuclear matter densities and to variations in the optical potential strengths. (AU)
