Abstract: Angular distributions of the 9 Be + 15 N elastic and inelastic scattering were measured at E lab ( 15 N) = 84 MeV ( E c.m. = 31.5 MeV) for the 0–6.76 MeV states of 9 Be and 0–6.32 MeV states of 15 N. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, spin reorientations of 9 Be in ground and excited states and 15 N in excited states as well as the most important one- and two-step transfer reactions were included in the channels-coupling scheme. The parameters of the 9 Be + 15 N optical potential of Woods–Saxon form as well as deformation parameters of these nuclei were deduced. The analysis showed that the 9 Be + 15 N pure potential elastic scattering dominates at the forward angles whereas the ground state spin reorientation of 9 Be gives a major contribution to the elastic scattering cross sections at the large angles. Contributions from particle transfers are found to be negligible for the present scattering system. [ABSTRACT FROM AUTHOR]
