【 摘 要 】

We analyze fusion hindrance phenomena involving heavy nuclei using the microscopic time-dependent Hartree-Fock theory combining with a macroscopic equation of motion with a friction term. We find that a barrier structure disappears in the obtained potentials in heavy systems. We show that main contribution to extra-push energy comes from the increase in dynamical potential.
