Popis: Existing data for the 6Li + 16O elastic scattering at $ E_{c.m.}=3.27$ -36.8MeV were analyzed within the optical model and coupled-reaction-channels method. The 6Li + 16O elastic and inelastic scattering as well as the reorientation of 6Li and the simplest transfer reactions were included in the coupled-channels scheme. The 6Li + 16O 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 6Li reorientation and transfer reactions to the 6Li + 16O 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 6Li + 16O deduced potential is in reasonable agreement with that of a corresponding folding potential. The isotopic difference between the 6Li + 16O and 7Li + 16O optical potentials is larger for the imaginary potentials.
