Abstract: | The aim of present work is to carry out an extensive theoretical investigation of the decay properties, and patterns of a variety of superheavy nuclear systems formed in heavy ion reactions. This investigation has been performed within the framework of Preformed cluster model (PCM) and Dynamical cluster decay model (DCM). The PCM is applied to understand the ground state decays such as -emission and heavy particle radioactivity (HPR), whereas DCM is applied to account for the decay of hot (E6=0) and rotating (`6=0) nuclei formed in low energy heavy ion reactions. The deformation and orientation effects of nuclei are explicitly included in these formalisms. The thesis is organized into seven chapters and a brief outline of the work is given below. Chapter 1 gives the general introduction related to present work, which includes the broad outline of experimental and theoretical developments related to the dynamics of hot and rotating compound nuclei in the superheavy mass region. A detailed discussion is made about the formation and decay processes of superheavy nuclei. The cold and hot fusion processes are described, which follows by various decay channels such as neutron evaporation, fusion-fission and quasi-fission. In addition to this, the ground state decays such as -decay and heavy particle radioactivity (HPR) are also explained for overall understanding of nuclear dynamics in superheavy region. Besides this, the role of excitation energy, deformations and orientations are discussed in view of reaction dynamics governed 1 2 via heavy ion collisions. Chapter 2 gives the details of the Preformed cluster model (PCM) and Dynamical cluster decay model (DCM) which are used to address the ground state and excited state decay patterns of nuclei. DCM is formulated from PCM (applied for ground state decays) by employing the temperature effects in its various interaction terms. Both models are based on the Quantum Mechanical Fragmentation Theory (QMFT). |
