A theoretical study on quasifission and fusion–fission processes in heavy-ion collisions

The stochastic mean-field (SMF) technique beyond the time-dependent-Hartree-Fock approach is used to explore the primary mass yields of quasifission fragments in the 58 Fe + 208 Pb reaction at the bombarding energy E c.m. = 238.5 MeV, 50 Ti + 208 Pb reaction at E c.m. = 237 MeV, and in the 36 S + 238 U reaction at E c.m. = 151.1 MeV. A statistical de-excitation model, GEMINI++ code, is used for calculating the primary mass yields of fusion–fission fragments after the de-excitation processes of primary products in the same systems. The obtained results are compared with available experimental data. Analysis of SMF and GEMINI++ calculations exhibit a good agreement with the corresponding experimental results, signifying the reliability of our approach in describing the fragment mass yields for the specific reaction systems.
