Abstract
The available experimental differential cross-section data for the Li-6+C-40 nuclear system in the energy range of 20-240 MeV have been reanalyzed using the framework of the phenomenological optical model (OM), the semi-microscopic cluster folding optical model (CFOM), and the microscopic cluster folding model (CFM) motivated by the well-known cluster structure of Li-6. Reasonable fits to the experimental data have been obtained using OM, CFOM, and CFM over the entire energy range considered in this study. For the real cluster folding potential, the extracted average renormalization factors from CFM and CFOM calculations are 0.46 0.14 and 0.56 0.05, respectively. Due to the well-developed cluster structure of Li-6 and the effect of its breakup on other reaction channels, the strength of the real cluster folding potentials was required to be reduced by similar to 44%-54% in order to describe the experimental data.
