Abstract

Elastic scattering differential cross sections were measured for the 28Si+58Ni system at sub-barrier energies. The corresponding nuclear potential was compared with earlier results of systems like A+58Ni. The present data also allowed the determination of the 28Si nuclear density through an unfolding method. The experimentally extracted 28Si density values are compared with those previously obtained for the 4,6He, 12C, 16,18O nuclei. We present a critical discussion of the absolute precision obtained for the density parameters extracted from the data analyses.
