Abstract: Angular distributions of the ⁷Li + ¹⁴N elastic and inelastic scattering as well as the ⁷Li(¹⁴N, Х) reactions with production of ^13,15,16N + ^8,6,5Li, ^11,12,13,14С + ^10,9,8,7Ве, ^10,11,12В + ^11,10,9В nuclei and others were measured at E_lab(¹⁴N) = 80 MeV. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, reorientations of ⁷Li and ¹⁴N in ground and excited states as well as the prominent one- and two-step transfers were included in a channels-coupling-scheme. The ⁷Li + ¹⁴N optical potential parameters for ground and excited states of ⁷Li and ¹⁴N as well as deformation parameters of these nuclei were deduced. The contributions of one- and two-step transfers in the ⁷Li + ¹⁴N elastic and inelastic scattering channels were estimated.

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