A complete set of analyzing powers ({ital i}T{sub 11}, T{sub 20}, T{sub 21}, and T{sub 22}) are reported for the elastic scattering of 50 MeV {sup 6} L{rvec i} by {sup 12}C. They are as large as or larger than those measured earlier for 30 MeV {sup 6}L{rvec i}. A combined optical model analysis of both energies shows T{sub 21} to arise from the tensor interaction, T{sub 20} to involve a combination of tensor and {ital J}-dependent interactions, and {ital i}T{sub 11} to be the most complicated, arising from an explicit spin-orbit, as well as tensor and {ital J}-dependent interactions. A coordinate transformation of the data and calculations, suggested in the earlier work of Hooton and Johnson, provides the clearest evidence for the need of a tensor interaction to describe {sup 6}L{rvec i} scattering. Examining the optical model calculations in terms of transferred angular momentum amplitudes provides further insight into the role played by each interaction. Also presented are the analyzing powers for the {sup 4}He({sup 6}Li,{sup 4}He) polarimeter reaction at this higher bombarding energy.
