Abstract

Collective clusterization approach of dynamical cluster decay model (DCM) has been applied to study the attributes of hot (T ≠ 0) and rotating ( ≠ 0) nuclei lying in heavy and superheavy mass regimes. We present here an overview of the characteristic fission decay properties such as shell effect, role of entrance channel, quadrupole (β 2) deformations and impact of hot (equatorial) compact orientation degree of freedom in comparison to cold (polar) elongated configuration. The presence of non-compound nucleus process, i.e., quasifission, is also investigated. Apart from studying the decay of excited state nuclei, the dynamics of heavy particle cluster emission is also addressed using the preformed cluster model (PCM).
