Fission Dynamics of 268 Sg Formed in 30 Si+238 U Reaction Around the Coulomb Barrier.

Abstract

The aim of present work is to study the possible decay modes of the nuclear system at energies around the Coulomb barrier. In the process, issues related to fusion-fission fragments, deformation and orientation effects, etc., are investigated. The tough challenges in nuclear perspective can be met only by developing and establishing clear understanding of related phenomena on the theoretical front, which could be utilized to plan and implement the predictions through experiments. A number of factors and properties influence the fusion-fission process and hence need to be handled with proper care in order to make meaningful predictions. The Dynamical Cluster Decay Model (DCM) is used to investigate the Fusion- fission of 268Sg formed in 30Si+238U reaction around the Coulomb barrier. The calculations have been done in the framework of Dynamical Cluster decay Model (DCM). We have calculated the fission cross-sections in reference to available experimental data. The decay has been analysed for the quadrupole (β2) deformed fragmentation. The calculated cross-sections compare nicely with the available experimental data within one parameter fitting, the neck length ΔR.
