Abstract

The yields of quasifission fragments in the reaction at are investigated in the framework of the stochastic mean field (SMF) approach based on the Skyrme-TDHF calculations. A method which combines the microscopic time-dependent Hartree–Fock (TDHF) theory with a statistical de-excitation model, GEMINI++, is used for calculating the yields of fusion-fission fragments after de-excitation processes of primary reaction products which is assumed to be dominated by neutron emission in the present system. Results are compared with available experimental data. It is shown that including secondary de-excitation process by particle emission gives a good agreement with the experimental data.
