Narrow Results

In this contribution we present the one-body dissipation dynamics in the fully three-dimensional time-dependent Hartree-Fock (TDHF) theory. The calculations were performed with modern Skyrme energy functionals plus tensor terms and without any symmetry restrictions. The energy dissipation was revealed to decrease in deep-inelastic collisions of the light systems as the bombarding energy increases owing to the competition between collective motion and single-particle degrees of freedom. The role of spin-orbit and tensor force was given particular emphasis. The spin-orbit force causes a significant enhancement of the dissipation. About 40%~65% of the total dissipation depending on the different parameter sets was predicted to arise from the spin-orbit force. The fusion cross section without tensor force overestimates the experimental value by about 25%, while the calculation with tensor force T11 has a good agreement with experimental cross section.

We show that the microscopic TDHF approach provides an important tool to shed some light on the nuclear dynamics leading to the formation of superheavy elements. In particular, we discuss studying quasifission dynamics and calculating ingredients for compound nucleus formation probability calculations.
