Double folding analysis of α+12C elastic scattering using different effective interactions

The elastic scattering angular distributions of α+12C at energies ranging from 48.7 MeV to 386 MeV were analyzed in the framework the double folding optical Model (DFOM). The DFOM potential is used with three different nucleon-nucleon (NN) effective interactions. The three interactions are the density- and energy-dependent, CDM3Y6, the São Paulo (SPP2), and the energy-independent Brazilian Nuclear Potential (BNP). The optical potential (OP) is generated using semi-microscopic (SM) and fully microscopic (FM) methods. It is found that SPP2 and CDM3Y6 are more appropriate to reproduce all experimental data than BNP. The real and imaginary potential parameters and their volume integrals, and the reaction cross-sections of the system are given for each effective interaction model.
