Angular distributions of the 9Be(11B, 12C)8Li reaction were measured (Warsaw cyclotron C-200) at Elab(11B)= 45 MeV for the transitions to the ground and excited states of 12C and 8Li.
The data were analysed by the coupled-reaction-channel method [1]. The elastic and inelastic scattering of 9Be + 11B and one- and two-step transfers were included in the channel coupling scheme. The optical model (OM) potentials of Woods-Saxon type with volume absorption were used for both entrance and exit reaction channels. The OM parameters obtained from the 9Be + 11B elastic scattering data at different energies were taken from Ref. [2] for the entrance reaction channel.
It was found that the proton transfer dominates in the 9Be(11B,12C)8Li reaction. The 3He-transfer (curve <3He> in Fig. 1) and two-step transfers are rather negligible. The 12C + 8Li OM parameters were deduced.
