Neutron transfer dynamics and doorway to fusion in time-dependent Hartree-Fock theory
We analyze the details of mass exchange in the vicinity of the Coulomb barrier for heavy-ion collisions involving neutron-rich nuclei using the time-dependent Hartree-Fock (TDHF) theory. We discuss the time dependence of transfer and show that the potential barriers seen by individual single-particle states can be considerably different than the effective barrier for the two interacting nuclei having a single center of mass. For this reason we observe a substantial transfer probability even at energies below the effective barrier.
