Elastic and inelastic scattering of 10B ions by 6Li nuclei at energy 51 MeV

Abstract

New experimental data of angular distributions for the elastic and inelastic scattering of 10B ions by 6Li nuclei were obtained at the energy Elab(10B) = 51 MeV for the ground and excited 2.18 – 5.7 MeV states of 6Li and 0.7 – 6.56 MeV states of 10В. These elastic and inelastic scattering data and known from literature data of elastic scattering of 6Li ions by 10В nuclei at energy Elab(6Li) = 30 MeV were analyzed within coupled-reaction-channels method. The 6Li + 10B elastic and inelastic scattering data, spin reorientation of 6Li and 10В, as well as more important transfer reactions, were included in the channels-coupling scheme. The Woods - Saxon potential parameters, as well as 6Li and 10В deformation parameters, were deduced. The mechanisms of the 6Li + 10В inelastic scattering were studied within the model of collective nuclei excitations, the differences of the 6Li + 10В elastic scattering from using 6Li + 10В, 7Li + 10В and 6Li + 11В potentials were observed, the contributions of one- and two-step transfers were deduced using spectroscopic amplitudes for transfer particles calculated within the translation invariant shell model.
