Multistep processes in the 12C(6Li,d) stripping reaction

The results of extensive coupled-reaction-channel calculations are compared with the cross section and new analyzing power data for the C-12(Li-6,d)O-16 reaction leading to the 0.0-MeV 0(+), 6.13-MeV 3(-), 6.92-MeV 2(+), 8.87-MeV 2(-), and 10.35-MeV 4(+) states of O-16 at Li-6 bombarding energies of 34 and 50 MeV. All the analyzing power data at both energies and all the cross section data at 50 MeV, with the exception of that for the C-12(Li-6,d)O-16 transition to the 0.0-MeV 0(+) state of O-16 are presented here for the first time. These results suggest that there are significant multistep contributions to transfers leading to the 0(+) and 3(-) states, while those leading to the 2(+) and 4(+) states may be reasonably well described by simple direct alpha transfer. The importance of multistep effects is found to increase with increasing bombarding energy.
