New angular distribution data for 7Li + 14N elastic and inelastic scattering at the energy
MeV (c.m. 26.7MeV) are presented. The data were analyzed within the optical model and the coupled-reaction-channels method using a channels-coupling scheme that included the 7Li and 14N inelastic scattering channels, spin reorientations of 7Li and 14N as well as most important transfer reactions. The low-energy excited states of 7Li and 14N were assumed to be collective in nature. The 7Li + 14N potential parameters as well as deformation parameters of 7Li and 14N were deduced. The 7Li + 14N potential and the data were compared with those of 6Li + 14N to observe isotopic differences. The enhanced large-angle elastic and inelastic scattering data are shown to have a large contribution from the ground-state reorientation of 7Li.
