Abstract

The quasi-elastic scattering data of ⁷Li + ¹²⁰Sn
reaction at E_Lab = 19.5, 20.5, and 25.0 MeV incident energies have
been reanalyzed within the framework of the optical model. In order to obtain
the real potential, seven different nuclear potentials have been used. The
imaginary potential has been assumed in Woods-Saxon form. The theoretical
results have been compared with each other as well as the experimental data.
