Investigation of possible multi-modal fission modes in ²³⁵U(n_th,f) following fission fragment spectroscopy

In the actinide region, the nuclear fission reaction is the most dominating exit channel following the formation of a heavy compound nucleus. In this process, the excited compound nucleus splits into two smaller primary fission fragments (FFs) of intermediate masses. We report the newly obtained results from the multimodal analysis of the FFMD of the fissioning system, ²³⁵U(n_th,f). The FFMD of the fissioning nucleus, ²³⁶U at an excitation energy (E_ex) of about 6.5 MeV has been extracted using the Fission Fragment Spectroscopy (FFS) technique following the prescription of.
