| Abstract: | How to produce neutron-rich heavy nuclei is one of the hot topics in nuclear physics, multinucleon transfer reaction would be a possible route to synthesize these nuclei. The time-dependent Hartree-Fock (TDHF) theory is employed to study the multinucleon transfer reaction 136Xe+198Pt at Ec.m.=645 MeV. The nucleon transfer process, energy dissipation and orientation of the deformed reactants on the reaction are investigated. The state-of-art statistical model GEMINI++ is adopted to investigate the deexcitation process of the excited primary fragments. The secondary isotopic production cross sections of the projectile-like fragment are compared with the experimental data. The results indicate that the data of few transfer channels can be well reproduced by TDHF. Discrepancy is observed for large transfer channels and the possible reasons are discussed. |
