An extensive and consistent coupled-channel analysis of the elastic, inelastic, one- and two-neutron transfer, and fusion experimental cross sections for the ${}^{18}\mathrm{O}$+${}^{58}\mathrm{Ni}$ system, in the energy range $35.1\le E_{\mathrm{LAB}}\le 65.0$ MeV, is described. In the calculations, we have used the São Paulo potential as the bare interaction. Our results show a quite different role played by the peripheral couplings on the fusion process as compared with previous analyses using simplified coupled-channel models. The results reported in the present work are an important tool for understanding the recently reported systematic failure of the Woods-Saxon nuclear potential to describe both fusion and elastic scattering processes.
