Abstract: New experimental data of angular distributions for the elastic and inelastic scattering of ¹⁰B ions by ⁶Li nuclei were obtained at the energy E_lab(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 E_lab(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.
