Elastic and inelastic scattering of 13C + 18O versus 12C + 18O and 13C + 16O

Complete angular distributions of the 13C + 18O elastic and inelastic scattering were measured at the energy Elab(O18)=105 MeV (Ec.m.=44.03 MeV). These and the 13C + 18O scattering data taken from the literature at the energies Ec.m.=6.29-13.94 MeV were analyzed within the optical model and coupled-reaction-channels methods. Sets of Woods-Saxon 13C + 18O optical potential parameters were obtained. The 13C + 18O scattering data and deduced potential parameters are compared with those for 12C + 18O and 13C + 16O previously measured and analyzed. The 13C + 18O elastic scattering is well described by potential scattering over its complete angular range. The 13C + 18O inelastic-scattering data were well described over the entire angular range as arising from collective excitations of the states in the target and projectile nuclei.
