Abstract.

Angular distributions of the 12C( 11B, 15N) 8Be reaction were measured at the energy Elab(11B) = 49 MeV for the transitions to the ground and 2.94 MeV (2+) excited state of 8Be and to the ground and 5.270 MeV (5/2+) + 5.299 MeV (1/2+), 6.324 MeV (3/2-), 7.155 MeV (5/2+) + 7.301 MeV (3/2+), 7.567 MeV (7/2+) excited states of 15N. The data were analyzed by the coupled-reaction-channel method. The elastic, inelastic scattering and one- and two-step transfers were included in the coupling scheme. The data of the 12C( 11B, 8Be) 15N reaction at Ecm = 9.4-17.8 MeV known from the literature, were also included in the analysis. The mechanism of the 12C( 11B, 15N) 8Be reaction and the optical-model potential parameters for the 15N + 8Be channel were deduced. The energy dependence of the optical-model parameters for the 15N + 8Be channel was obtained.
