摘要

The quasifission dynamics in the reaction 48Ca+244pu is investigated in the framework of time-dependent Hartree-Fock (TDHF) theory.The calculations are performed in three-dimensional Cartesian coordinate without any symmetry restrictions.The full Skyrme energy functional is incorporated in our TDHF implementation.The quasifission dynamics is quite sensitive to the angular momentum of colliding system.The contact time of quasifission decreases as a function of angular momentum and then forms a plateau with small oscillations.The quasifission process is accompanied by an important multi-nucleon transfer.The quantum shell effect plays a crucial role in the mass and charge of quasifission fragments.The mass-angle distribution of the fragments is calculated,which can be compared directly with future experiments.
