The elastic scattering of 6,7Li+28Si reactions has been analyzed in the
framework of the double folding optical model. Semi-microscopic folded
potentials are generated based on the alpha (α)-cluster structure of the colliding
nuclei. Successful reproduction of the observed angular distributions of the
elastic scattering differential cross section and reaction cross sections has
been obtained at different energies using the derived potentials. A microscopic
folding approach based on the effective DDM3Y nucleon–nucleon interaction
and the nuclear matter densities of the interacting nuclei is also considered.
