Abstract: Angular distributions of the ⁷Li + ¹¹B elastic and inelastic scattering were measured at E_lab(¹¹B) = 44 MeV for the transitions to the ground and excited states of ⁷Li and ¹¹B. These data and those known from literature only at E_lab(⁷Li) = 34 MeV were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, reorientations of ⁷Li and ¹¹B in ground and excited states as well as the prominent one- and two-step transfers were included in the channels-coupling-scheme. The ⁷Li + ¹¹В optical potential parameters for ground and excited states of ⁷Li and ¹¹B as well as deformation parameters of these nuclei were deduced. The energy dependence of ⁷Li^(*) + ¹¹B^(*) optical potential parameters was studied.
