The experimental work reported consists of (1) the measurements of the angular distributions for the scattering of $\sp6$Li from the targets $\sp9$Be, $\sp{12}$C, and $\sp{16}$O at a lithium bombarding energy of 50 MeV, and (2) the measurement of the tensor polarization of the FSU polarized $\sp6$Li source. 50 MeV data were taken for elastic and inelastic scattering to the 2$\sp+$ (4.44 MeV), 0$\sp+$ (7.65 MeV), and 3$\sp-$ (9.64 MeV) states in $\sp{12}$C, the 5/2$\sp-$ (2.43 MeV) state in $\sp9$Be, and the unresolved 0$\sp+$/3$\sp-$ (6.05/6.13 MeV) and $2\sp{+}/1\sp{-}$ (6.92/7.12 MeV) states in $\sp{16}$O. The measurement of the tensor polarization of the FSU $\sp6$Li source allowed the absolute polarization efficiency of the source-accelerator system to be determined. / The analytical work reported consists of a determination of the energy dependence of the optical potential parameters for $\sp6$Li + $\sp{12}$C scattering over the energy range from 11 MeV to 210 MeV. This has been attempted previously and the results have not been successful. A large body of data for $\sp6$Li + $\sp{12}$C allows more severe constraints than in previous studies. The inclusion of an angular momentum-dependent imaginary potential provides a good description of the elastic scattering data and the parameters determined in this study are smoothly varying with energy using Woods-Saxon form factors for the real and imaginary potentials. Inelastic scattering to the 2$\sp+$ (4.44 MeV), 0$\sp+$ (7.65 MeV), and 3$\sp-$ (9.64 MeV) states in $\sp{12}$C are described well using the constructed energy dependent potentials in DWBA calculations. Analysis using the double folded real potential and a Woods-Saxon imaginary potential were performed on the same $\sp6$Li + $\sp{12}$C scattering data from 11 MeV to 210 MeV. / The scattering data for 50 MeV $\sp6$Li scattering from the targets $\sp{16}$O and $\sp9$Be are described using optical potentials and DWBA calculations. Less information is obtained from these analyses because data do not exist at this time over a wide enough energy range to provide a constraint on the interaction potentials. / Source: Dissertation Abstracts International, Volume: 50-08, Section: B, page: 3543. / Major Professor: Kirby W.
