Abstract
In this paper, the radial sensitivity of the elastic scattering cross-section for the He-4 and He-6 on Sn-120 have been examined at energies near the Coulomb barrier. We also investigate the variation of the potential radius depending on the incident energy for the He-4 + Sn-120 and He-6 + Sn-120 systems. Especially, we have taken care of to stay within one family for He-4 + Sn-120 elastic scattering, i.e., using V-0 real depth have not been changed by more than 20-30%.
