Pre-scission proton multiplicity spectra in ¹⁶O + ²³²Th reaction at E_Lab = 96 MeV

Despite the continued intensive research for the last several decades, the heavy-ion induced fusion-fission reveals often surprises. Several fission observables from the direct detection of fission fragments (FFs) such as the mass distributions, angular-distributions etc. deviate the expectations of fission decay from an equilibrated compound nucleus when it is induced by heavy-ion fusion reactions. Traditionally, several terms, such as "quasi fission", "pre-equilibrium fission", "slow quasi fission", etc. have been associated with aforesaid different observations. However, the underlying mechanism is not very well understood. Details about the moving source fit to disentangle the contributions in proton multiplicity from different stages of the fusion-fission process will be presented
