Collective analysis of theoretical and experimental studies suggests that the nuclei of heavy
mass region are radioactive, and exhibit α decay, cluster radioactivity, heavy particle
radioactivity and spontaneous fission. The dominance of one or more decay modes rely on
the stability of parent nucleus and the fragmentation structure associated with them. In view
of this, the decay analysis of 254Es radioactive nucleus is carried out using collective
clusterization approach of preformed cluster model (PCM) that treats the competing decay …
