Abstract
The possible decay modes of even [Formula: see text] [Formula: see text]Cm parents have been analyzed to explore the relative emergence of various ground state emission mechanisms using the collective clusterization approach. Based on the collective availability of [Formula: see text], cluster and spontaneous fission (SF) experimental half-life data, we limit our study to isotopes of Cm. In view of this, the most probable decaying fragments from [Formula: see text]Cm are identified in different mass regions and a comprehensive analysis of the shell closure effect of the decay fragments corresponding to different mass domains is carried out within the methodology of Preformed Cluster Model (PCM). The isotopic analysis of the mass distributions and the related barrier characteristic quantities are investigated in view of ground state decay of [Formula: see text]Cm isotopes. The PCM calculated [Formula: see text] and SF half-lives compare nicely with the experimental data and the predictions are made on cluster and heavy-cluster decay of Cm isotopes, where experimental data is not available. It will of further interest to validate these predictions by performing corresponding experiments.
