Sub-barrier fusion of weakly bound Li6 with Ni58

Evaporation-proton yields were measured for the fusion of the weakly bound nucleus $^{6}\mathrm{Li}$ on a $^{58}\mathrm{Ni}$ 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 $^{6}\mathrm{Li}+(^{59}\mathrm{Co}, ^{64}\mathrm{Ni}, ^{64}\mathrm{Zn})$ systems shows good consistency except for some data spread at the lower energies.
