Sub-barrier fusion of weakly bound Li 6 with Ni 58

Evaporation-proton yields were measured for the fusion of the weakly bound nucleus Li-6 on a Ni-58 target at six near-or sub-barrier bombarding energies. Effects of the one-neutron transfer reaction were estimated and corrections made. Total-fusion cross sections were deduced using calculated proton multiplicities. The resulting fusion excitation function shows a considerable enhancement with respect to calculations for a bare potential. Inelastic couplings are estimated to have insignificant effects on such fusion. The sum of total fusion plus one-neutron transfer cross sections nearly saturates the total reaction cross section in the energy region measured. Comparison with previous results appropriately scaled for the Li-6 + (Co-59, Ni-64, Zn-64) systems shows good consistency except for some data spread at the lower energies.
