Abstract: Experimental data of the ⁶Li + ¹⁶O elastic scattering at E_c.m. = 3.27 - 36.8 MeV known from literature, 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 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 accounting dispersion relation between real and imaginary parts of the potential. Contributions of the ⁶Li reorientation and transfer reactions to the ⁶Li + ¹⁶O elastic scattering data were estimated at different energies. Real part of the ⁶Li + ¹⁶O deduced potential and the ⁶Li + ¹⁶O folding-potential are compared. The isotopic differences between the ⁶Li + ¹⁶O and ⁷Li + ¹⁶O were studied.

Keywords: heavy-ion elastic scattering, optical model, coupled-reaction-channels method, folding-model, spectroscopic amplitudes, optical potentials, reaction mechanisms.
