Abstract
Using the alpha (alpha)-cluster structure of C-12 nucleus, two versions of the C-12+C-12 real double folded optical potentials have been generated based upon effective alpha-alpha, alpha-nucleon (N) and N-N interactions. The obtained potentials, in conjunction with shallow phenomenological Woods-Saxon imaginary parts, successfully reproduce the elastic scattering differential cross section for 12 sets of data over the broad energy range 70-360 MeV. No renormalization of the real folded potentials is required to fit the data. The energy dependence of the extracted real and imaginary volume integrals and total reaction cross section is investigated.
