Abstract
Using the phenomenological optical potential and two different semi-microscopic potentials, namely double folding and cluster folding (CF), the available experimental data for 6Li elastically scattered from [Formula: see text]C nucleus at energies 50–600[Formula: see text]MeV are reanalyzed. On the basis of the well-known cluster structure of 6Li as a composite nucleus consisting of a core “alpha” with a valence particle “deuteron” orbiting this core, special attention was paid to the CF potential. Elastic scattering data for 6Li+[Formula: see text]C system plotted as a function of momentum transfer showed that the real Coulomb nuclear interference region is independent of the bombarding energy. The aforementioned structural behavior for the data could be used to define the potential with some certainty. In addition to a Woods–Saxon imaginary potential of fixed radius, the real part of the potential derived from the cluster structure of 6Li was successful in reproducing the experimental data in the whole angular range. Coupled channel (CC) calculation effects are also performed by coupling to 6Li resonant state ([Formula: see text], [Formula: see text][Formula: see text]MeV).
