Role of spin effects in C-12(Li-6,d)O-16(g.s.)

The first complete set of analyzing powers for the C-12((6)<(Li)over bar>,d )O-16(g.s.) reaction at E(Li-6) = 50 MeV is reported. It was possible to si multaneously describe Li-6+C-12 elastic scattering and its analyzing powers , d+O-16 elastic scattering, and the C-12((6)<(Li)over bar>,d)O-16(g.s). tr ansfer data. This 0(+)-->0(+) transfer is used to probe the role of spin-de pendent interactions in this reaction, including, the Li-6 D state, with fi nite-range-distorted-wave-Born-approximation calculations. It is found that the exit channel spin-orbit d+O-16 interaction produces the transfer analy zing powers, but that the shape and magnitude of the transfer angular distr ibution is determined by the central Li-6+C-12,d d+O-16 interactions. The l imited knowledge of the size of the alpha+C-12 system is shown to be the ma jor uncertainty in using the C-12(Li-6,d)O-16 reaction to determine absolut e alpha+C-12 spectroscopic factors.
