Abstract: Angular distributions of the 7Li + 12C elastic and inelastic scattering as well as the 7Li(14N, Х) reactions with exited stable and unstable nuclei with Z = 3 - 6 were measured at Elab(12C) = 115 MeV. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, reorientations of 7Li in ground and excited states as well as more important transfer reactions were included in the channels-coupling-scheme. 7Li + 12C optical potential parameters for ground and excited states of 7Li and 12C as well as deformation parameters of these nuclei were deduced. The contributions of one- and two-step transfers in the 7Li + 12C elastic and inelastic scattering channels were estimated.
Keywords: heavy-ion scattering, optical model, coupled-reaction-channels method, spectroscopic amplitudes, optical potentials, reaction mechanisms.
