The cluster folding model analysis for the elastic scattering of 6Li and 6He on 12C
Abstract.To investigate the refractive effect in the scattering of loosely bound and exotic nuclei, the double-folding-cluster potential has been adopted in the optical model analyses of the elastic scattering of 6Li + 12C and 6He + 12C. The experimental angular distributions are reproduced very well over a wide energy range. For 6Li + 12C, the energy dependence of the optical potential agrees well with the dispersion relation. For the elastic scattering of 6He + 12C at intermediate energies, the refractive effect is predicted by the present calculation, accompanied by the abnormally weak absorption.
