Energy dependence of the 6Li + 16O scattering and isotopic differences between potentials of the 6,7Li + 16O interactions

Abstract

Experimental data of the 6Li + 16O elastic scattering at Ec.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 accoounting dispersion relation between real and imaginary parts of the potential. Contributions of the 6 Li 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.
