Sub-barrier fusion cross sections of (36)S + (64)Ni have been measured down to similar or equal to 3 mu b. The logarithmic slope of the fusion excitation function has a steep rise in the barrier region with decreasing energy and saturates at lower energies. The data can be reproduced within the coupled-channels model using a Woods-Saxon potential with a large diffuseness. The slope saturation is analogous to what has been observed for (36)S, (48)Ca + (48)Ca, while for heavier systems the slope increases steadily below the barrier.

Abstract
Sub-barrier fusion cross sections of (36)S + (64)Ni have been measured down to similar or equal to 3 mu b. The logarithmic slope of the fusion excitation function has a steep rise in the barrier region with decreasing energy and saturates at lower energies. The data can be reproduced within the coupled-channels model using a Woods-Saxon potential with a large diffuseness. The slope saturation is analogous to what has been observed for (36)S, (48)Ca + (48)Ca, while for heavier systems the slope increases steadily below the barrier.File in questo prodotto:
