Analysis of different decay modes of 210rn* nucleus at above barrier energies

Abstract

Today, in an era of scientific research and technologies, one needs to update his/her knowledge in reference to latest developments in the concerned area. In context of nuclear physics, it becomes very important to have proper understanding of the nuclear reaction dynamics and the related phenomena associated with nuclear structure aspects. Various experimental as well as theoretical efforts are going on to have a better understanding of the nucleus and its properties. The shape and size of the nucleus is very important part in the reaction dynamics as majority of the nuclear systems are deformed to some order. Therefore, to have better understanding of the reaction dynamics, Dynamical cluster model (DCM) has been applied to study the decay patterns of Heavy Mass Nucleus210Rn formed in heavy-ion reaction induced using 16O projectile. The DCM based cross-sections agree fairly with available data by anticipating some Quasi-Fission component at two highest energies. The following reaction is studied and worked upon over a wide range of energies. 16O+ 194Pt→210Rn→A1+A2 Where A1 and A2 represent the mass of decaying fragments in collective clusterization approach adopted in context of a well known theory known as Quantum Mechanical Fragmentation Theory (QMFT), which was developed in Frankfurt School about four decades from now. This dissertation consists of three chapters. Chapter 1: Chapter-1 gives an overview of the nuclear reaction dynamics, associated features such as nuclear shapes, associated decay mechanisms and importance of the work carried out in this dissertation. Chapter 2: Chapter-2 consists of the description of Dynamical Decay Cluster Model (DCM). It carries the various potentials used in DCM along with other parameters such as preformation factor, barrier penetrability, etc. The deformation effects of nuclear systems are duly included in the framework of DCM. Chapter 3: Chapter-3 consists of the details of the DCM based calculations for 16O+194Pt→210Rn→A1+A2 reaction in reference to the possibility of different decay modes over a wide range of incident energies.
