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