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.
