A Theoretical Study of Heavy Ion Collisions and Related Dynamical Aspects

Abstract

In this thesis, a comprehensive study is carried out to explore the formation and decay mechanism of various nuclear systems formed in heavy ion induced reactions. The Wong and `-summed Wong formula are applied to account for the formation process, whereas dynamical cluster decay model (DCM) employed to address the decay paths of hot and rotating compound nuclei. To investigate both the pro cesses, two sets of nuclear interaction potentials are employed i.e. one based on the proximity based pocket formula and other obtained from the Skyrme Energy Den sity Formalism (SEDF). It is relevant to mention here that, the angular momentum, temperature, deformations and orientation eand#64256;ects of the reacting partners and de caying products are aptly contained respectively in Wong and DCM model. The thesis is organized into seven chapters, a transient discussion of which is discussed below. Chapter 1 presents the brief account of heavy ion induced nuclear reactions governing the dynamics at low energy region. A literature survey on the formation and decay of compound nucleus is discussed in detail. To understand the mechanisms involved in fusion-and#64257;ssion processes and to extract related nuclear structure eand#64256;ects, a deep understanding of nucleus-nucleus interaction potentials is crucial, a brief interpretation of which is discussed in this chapter. Along with this, the deformation and orientation eand#64256;ects in view of dynamics governed via heavy ion reactions is discussed in brief. Chapter 2 describe the details of the methodology used to probe the formation and decay mechanism of heavy ion induced compound nucleus reactions. Wong for mula and its extended version i.e. `-summed Wong formula are used to study the formation phenomena.
