Abstract: Angular distributions of the ¹¹B + ¹⁵N elastic and inelastic scattering were measured at E_lab (¹⁵N) = 84 MeV. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, reorientations of ¹¹B and ¹⁵N in ground and excited states as well as the important one- and two-step transfer reactions were included in the channels-coupling-scheme. The ¹¹B + ¹⁵N optical potential parameters as well as deformation parameters of these nuclei were deduced. The contributions of one- and two-step transfers in the ¹¹B + ¹⁵N elastic and inelastic scattering channels were estimated.

Keywords: heavy-ion scattering, optical model, coupled-reaction-channels method, spectroscopic amplitudes, optical potentials, reaction mechanisms.
