Neutron Evaporation Analysis of 44Ca Induced Reactions on Trans Lanthenide Targets

Abstract

Dynamical cluster decay model (DCM) has been applied to study the dynamics of 44Ca induced reactions. The DCM based neutron based 44Ca-induced reactions on trans-lanthanide targets agree nicely with experimental data. The following reactions are studied and worked upon over a wide range of incident energies. 44Ca+158Gd →202Po* → 199Po+3n 44Ca+159Tb → 203At* → 200At+3n  44Ca+162Dy →206Rn* → 203Rn+3n This dissertation comprises of three chapters. Chapter-1 consists of the basic over-view of nuclear reactions, compound nucleus formation, neutron evaporation and deformations and orientations. Chapter-2 consists of the description of dynamical cluster decay model (DCM). It gives description about the various potentials used in DCM, mass-dependent level density parameter along with other parameters of the model. The deformation effects of decaying fragments are included in the framework of DCM. Chapter-3 consists of the details of the DCM based calculations for the above mentioned reactions and the fragmentation behaviour of the chosen reactions is analysed in view of preformation factor and barrier penetrability
