Abstract

The Dynamical Cluster-decay Model (DCM) has been employed to analyze the charge particle emission from Pb isotopes formed in highly asymmetric n-induced channel. The experimental data for -emission from Pb and p-emission from Pb is addressed nicely by optimizing the neck-length parameterR over an energy spread of 14-20 MeV. The comparative analysis of the decay profiles of Pb is carried out at common excitation energy, by analyzing the fragmentation structure at extreme angular momentum values. The relevance of sticking and non-sticking moment of inertia has also been analyzed for the light particle (LP) emission (asymmetric decay mode) and fission decay channel (symmetric decay mode). Besides this, the effect of mass of target nucleus on the reaction dynamics is explored by investigating the decay profiles of a lighter compound system formed under similar reaction conditions and the comparative analysis of the fragmentation behavior is carried out at common beam energy. The product is minimum for the p-emission from any excited parent nucleus, hence, it would be interesting to explore the charge distribution of the decaying fragments. This aspect is explored by employing charge dependent radius expression within the framework of DCM.
