Dynamics aspect of subbarrier fusion reaction in light heavy ion systems

Abstract

Subbarrier fusion of the 7Li+12C reaction is studied using an antisymmetrized molecular dynamics model (AMD) with an after burner, GEMINI. In AMD, 7 Li shows an α + t structure at its ground state and it is significantly deformed. Simulations are made near the Coulomb barrier energies, i.e., Ecm = 3 - 8MeV. The total fusion cross section of the AMD + GEMINI calculations as a function of incident energy is compared to the experimental results and both are in good agreement at E cm > 3MeV. The cross section for the different residue channels of the AMD + GEMINI at Ecm = 5MeV is also compared to the experimental results.
