摘要

Within the time-dependent Hartree-Fock (TDHF) approach, we investigate the impact of several ingredients of the nuclear effective interaction, such as incompressibility, symmetry energy, effective mass, derivative of the Lane potential, and surface terms on the exit channel (fusion vs quasifission) observed in the reaction U-238 + Ca-40, close to the Coulomb barrier. Our results show that all the ingredients listed above contribute to the competition between fusion and quasifission processes; however, the leading role in determining the outcome of the reaction is played by incompressibility, symmetry energy, and the isoscalar coefficient of the surface term. This study unravels the complexity of the fusion and quasifission reaction dynamics and helps us to understand the microscopic processes responsible for the final outcome of low-energy heavy-ion collisions in terms of relevant features of the nuclear effective interaction and associated equation of state (EOS).
