Influence of inelastic couplings on ³²S + ²⁴MG sub-barrier fusion

Abstract

Elastic, inelastic and mutual excitation angular distributions have been measured for ³²S+ ²⁴Mg at 65, 75, 56.3, 95 and 110 MeV of ³²S incident energy. The data have been analysed by optical model and coupled channel calculations. Energy-dependent optical potentials have been obtained which have been used to describe the ³²S + ²⁴Mg fusion data of Berkowitz et al ²). Barrier penetration and coupled channel models are compared. It is found that the energy-dependence of the empirical potentials is essential if a consistent simultaneous description of elastic, inelastic an fusion data is required.
