Elastic and inelastic scattering of 15N ions by 6Li nuclei at energy 81 MeV

Angular distributions of the elastic and inelastic scattering of 15N ions by 6Li nuclei were measured at the energy Elab(15N) = 81 MeV. The data were analyzed within the coupled-reaction-channels method (CRC). The elastic and inelastic scattering, spin reorientation of 6Li as well as the one- and tw...

Description
Summary:Angular distributions of the elastic and inelastic scattering of 15N ions by 6Li nuclei were measured at the energy Elab(15N) = 81 MeV. The data were analyzed within the coupled-reaction-channels method (CRC). The elastic and inelastic scattering, spin reorientation of 6Li as well as the one- and two-step transfer reactions were included in the channels-coupling scheme. The potential of Woods - Saxon form (WS) and double folded potential DF for the 15N + 6Li nuclei interaction were used in CRC-calculations. The WS potential parameters, deformation parameters of 6Li and 15N nuclei were deduced and the information about the role of other processes in the 15N + 6Li elastic and inelastic scattering was obtained. Spectroscopic amplitudes of nucleons and clusters, calculated according to a translational invariant shell model, were used in the CRC-calculations. It was established that the potential scattering and the 6Li spin reorientation are dominated in the 15N + 6Li elastic scattering. Contributions from particle transfers in this scattering were negligible. Comparing the 15N + 6Li and 15N + 7Li elastic scattering at the energy Elab(15N) = 81 MeV, it was found marked differences between the experimental data and interaction potentials (isotopic effects).
