Surface absorption in the ³²S + ²⁴Mg interactions at energies near the coulomb barrier

Elastic scattering of 32S on 24Mg has been measured at 65.0, 75.0, 86.3, 95.0 and 110.0 MeV lab energies, and the data were systematically analyzed with semi-phenomenological potentials. Using microscopic potentials we found similar results at the two lowest incident energies, for which we have compared both the microscopic and semi-phenomenological potentials. It appears that the absorption takes place in a narrow range at the nuclear surface and is mainly due to the low-lying collective surface states. © 1995.
