Existing data for the 6 Li + 16 O elastic scattering at -36.8MeV were analyzed within the optical model and coupled-reaction-channels method. The 6 Li + 16 O elastic and inelastic scattering as well as the reorientation of 6 Li and the simplest transfer reactions were included in the coupled-channels scheme. The 6 Li + 16 O potential parameters at different energies as well as their energy dependence were deduced by the use of the dispersion relation between the real and imaginary parts of the potential. The contributions of the 6 Li reorientation and transfer reactions to the 6 Li + 16 O elastic scattering channel were estimated at the different energies. It is found that the potential scattering dominates the interaction at smaller angles for all energies, with the transfers contributing significantly at larger angles at the highest energies studied. The real part of the 6 Li + 16 O deduced potential is in reasonable agreement with that of a corresponding folding potential. The isotopic difference between the 6 Li + 16 O and 7 Li + 16 O optical potentials is larger for the imaginary potentials.
