The results of two studies of the elastic and inelastic scattering of /sup 6/Li are reported. The analysis of the data in both studies was designed to determine if a moderately parameter-free description of /sup 6/Li scattering on several targets was possible. The philosophy here was to derive the real nucleus-nucleus interaction potential starting from a microscopic nucleon-nucleon interaction and summing over the contributions from both target and projectile nucleons. A Woods-Saxon imaginary potential was used for the absorptive part of the interaction potential. The inelastic transition strengths were obtained from electron scattering rather than treating them as free parameters. It was found that for the present inelastic /sup 6/Li scattering, the nuclear and Coulomb transition strengths are equal and are consistent with electron scattering. In the first study, elastic and inelastic scattering data extending to theta/sub c.m./ approx. = 175/sup 0/ are reported for /sup 6/Li + /sup 28/Si at 27 and 34 MeV. Optical model analyses of the elastic data were made using a variety of real potential forms. In the second study, differential cross sections for elastic and inelastic /sup 6/Li scattering from /sup 12/C at 24 and 30 MeV, and from /sup 16/O at 25.7 MeV were measured out to theta/sub c.m./ approx. = 170/sup 0/. Also by scattering /sup 12/C and /sup 16/O from /sup 6/Li, the inelastic cross sections for the excitation of the 3/sup +/(2.18 MeV) and the 2/sup +/(4.31 MeV) states of /sup 6/Li and an estimate of the continuum inelastic cross sections of /sup 6/Li were measured.
