Role of Spin Saturated and Unsaturated Interaction Potentials in Extended Thomas-Fermi Approach

Abstract

Abstract

The role of spin saturated and unsaturated interaction potentials have been studied in context of 23,25,27,29,31Al + 45Sc → 68,70,72,74,76Se* reactions using semiclassical Extended Thomas-Fermi (ETF) approach in the framework of Skyrme Energy Density Formalism (SEDF) under frozen density approximation. Finally, the -summed extended Wong Model is used to investigate the fusion evaporation cross-sections of 27Al + 45Sc reaction over a wide range of incident energies. The present work consists of three chapters. CHAPTER 1 Chapter1 contains the introductory part of spin saturated and unsaturated interaction potentials along with the knowledge of the nucleus-nucleus interactions. Besides this an emphasis is made on the module of semiclassical extended Thomas-Fermi approach and its possible use in the fusion evaporation and related phenomena. CHAPTER 2 Chapter2 consists of the description of the -summed Extended Wong-Model. In this description I have explained the advantage of using different Skyrme forces like SIII and GSk1 via nuclear proximity potential which is calculated from SEDF. The relevant details regarding inclusion of deformation effects and penetration probability etc are duly incorporated in this chapter. CHAPTER 3 Chapter3 consists of calculations and results. The calculations have been carried out for the spherical and deformed choice of nuclei in reference to the spin-orbit interaction potential for the isotopes of Al on fixed target 45Sc using Skyrme forces SIII and GSk1. The fusion evaporation cross-sections are calculated in the framework of -summed Wong Model using Skyrme Energy Density Formalism (SEDF) approach for 27Al + 45Sc reaction over a wide range of incident energies.
