Abstract

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.
