|Nuclear Reaction Dynamics Using Loosely Bound Projectile 9Be and Associated Incomplete Fusion Analysis
|Fission;Weakly Bound;Incomplete Fusion
|Abstract In order to study the nuclear reaction dynamics associated with 9Be+ 89Y reaction, dynamical cluster decay model (DCM) has been used. Calculations have been carried out over a broad set of center-of-mass energies varying from (Ec.m. =18.1-29.8 MeV). A comparative analysis of complete and incomplete fusion reaction is presented for weakly bound projectile “9Be”. All estimations are done using quadruple choice of fragments and optimum orientation approach. In addition to this, comparison of various isotopes of technetium (96, 98, 99, 100, 102, 104Tc) has also been studied by addressing their respective decay paths. This dissertation is focused on following three chapters. Chapter-1: Chapter-1 includes the basic impression of nuclear physics including its applications and benefits to mankind. In addition to this, various mathematical models dealing with nuclear structural properties are briefly discussed here. Furthermore, nuclear reactions and their types on the basis of distinct parameters like energy, mass and compound nucleus formation etc. are explained. Besides this, a description of compound nucleus formation and its successive decay mechanisms is briefly outlined in view of dynamical evolution of heavy ion induced collisions at low energy regime. Chapter-2: Chapter-2 consists of the methodology used to understand reaction dynamics of 9Be induced reaction(s). The Dynamical Cluster-Decay Model (DCM) is used to analyze the fragmentation behavior governed for complete fusion and incomplete fusion paths. Chapter-3: Chapter-3 gives an account of the analysis of the decay patterns governed via complete and incomplete amalgamation of 9Be projectile with medium mass target, and consists of DCM based calculations and the results obtained/conclusions drawn after performing the analysis of concerned reaction. Calculations are done over a wide range of incident energies and DCM based results are found in decent agreement with available experimental data.
