The elastic scattering vector analyzing powers for /sup 6/Li+/sup 16/O at 25.7 MeV and /sup 6/Li+/sup 12/C at 30 MeV have been measured. In addition, measurement of the vector analyzing power for inelastic /sup 6/Li scattering has been made for the 2/sup +/ (4.44 MeV) state in /sup 12/C. Excitation function data for /sup 6/Li+/sup 16/O elastic and inelastic scattering have also been measured at five angles for /sup 6/Li lab energies through the range 15--28 MeV in 375 keV steps. These data show the system to be resonance free at 25.7 MeV. The data have been analyzed in the coupled channels framework, employing the double folding model for the real part of the nuclear scattering potential. The coupling strengths in the coupled channels calculations were determined from inelastic scattering cross-section data directly. The elastic scattering vector analyzing powers arise from a complicated interference between channel coupling and spin-orbit contributions, whereas the /sup 12/C, 2/sup +/ inelastic vector analyzing power arises from the spin-orbit potential only. Inelastic scattering analyzing powers may allow the shape and strength of heavy-ion spin-orbit potentials to be investigated more clearly than do the elastic scattering analyzing powers. The normalization of the double-folded real potential was found to be in the range 0.85--1.00 in the coupled channel calculations, thus bringing the normalization of /sup 6/Li scattering into agreement with other projectiles.
