Role of saddle-to-scission dynamics in fission fragment mass distribution

Fission fragment mass distribution (FFMD) is an important tool to distinguish the complete fusion events from the non-compound events like quasi-fission, deep inelastic collision etc. Statistical model calculations have been applied successfully in the past to calculate the FFMD of thermal neutron induced fission. But, in case of heavy-ion induces fusion-fission reactions, dynamical models are more appropriate because of the presence of nuclear dissipation. In the present calculation, using Langevin dynamical equations, the effect of dissipation is shown in FFMD during the journey of the compound nucleus (CN) from saddle to scission configuration
