Elastic and inelastic scattering of 7Li + 18O versus 7Li + 16O

Angular distributions of the 7Li + 18O elastic and inelastic scattering were measured at the energy Elab(18O) = 114 MeV (32 MeV c.m.) in inverse kinematics. This technique allowed both small and large angle data to be collected simultaneously. The data were analyzed within the optical model and coupled-reaction-channels method to determine the potential parameters of 7Li + 18O scattering and reaction channels dominating the scattering. 18O inelastic scattering deformation parameters were obtained. The present data show that the 7Li + 18O system has a much stronger absorption when compared to previously measured 7Li + 16O data. The derived optical model parameters clearly show the scattering difference between two systems.
