Elastic scattering and fusion calculations for ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{63,65}$Cu

Coupled channels calculations that simultaneously predict elastic scattering and fusion reaction cross sections are compared with the corresponding available measurements for ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{63,65}$Cu collisions. The calculations can reproduce the main features of the fusion and elastic scattering data sets but only separately by using significantly different ion-ion potentials.
