Fusion and quasi-fission in heavy systems with the microscopic time-dependent energy density functional theory
Fusion hindrance, where fusion probability in heavy systems is strongly hindered compared with that in light and medium-mass systems, is analyzed by the microscopic time-dependent energy density functional theory. From trajectories obtained for fusion reactions, we extract nucleus-nucleus potential...

Fusion hindrance, where fusion probability in heavy systems is strongly hindered compared with that in light and medium-mass systems, is analyzed by the microscopic time-dependent energy density functional theory. From trajectories obtained for fusion reactions, we extract nucleus-nucleus potential and one-body energy dissipation for the entrance channel of fusion reactions in heavy systems. We find that a barrier structure disappears and an increase behavior is observed in the obtained potential, which are different from the cases of light and medium-mass systems and of the frozen density approximation. We show that main contribution to extra-push energy comes from the increase of potential energy because of dynamical effects.
