Sub-barrier fusion of 36S + 64Ni and other medium-light systems

Sub-barrier fusion cross sections of 36S + 64Ni have been measured down to ~3 microbarn. 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 di useness. The slope saturation is analogous to what has been observed for 36S+48Ca and 48Ca + 48Ca, while for heavier systems the slope increases steadily below the barrier.
