ResumoCoupled-channels calculations are presented tor elastic and inelastic 6Li + 12C scattering at Ec.m. = 16 MeV and 20 MeV, and for 6Li + 16O at 18.7 MeV. Excitation of states within 6Li, 12C and 16O are treated with rotational, rotation-vibration and vibrational models only. The 3+ 6Li and 2+ 12C states are strongly coupled to the elastic scattering and reduce the strengths of both the real and imaginary potentials. The 3− 16O state reduces only the strength of the imaginary potential. All other states are weakly coupled and have little effect on each other or the potential. The data are reasonably well described, with there being some preference for the 3− state in 12C to be K = 0. Excitation of the 02+ state in 12C requires a combination of β-vibration and monopole breathing-mode form factors. The deformation lengths found are in poor agreement with those deduced from electron or proton scattering.
