Abstract

We have analyzed the fusion dynamics of Ca2040+Ni2858,64 reactions by using the energy dependent Woods-Saxon potential (EDWSP) model and coupled channel model and subsequently the decay patterns of Cd*4898,104 nuclei are governed via the dynamical cluster-decay model (DCM). The influence of intrinsic degrees of freedom of colliding pairs, such as low lying surface vibrations and neutron transfer channels, are entertained within the context of coupled channel calculations. Interestingly, the energy dependence in the Woods-Saxon potential induces barrier modification effects (barrier height, barrier position, barrier curvature) in a somewhat similar way as that for coupled channel approach, hence adequately explains the observed fusion dynamics of Ca2040+Ni2858,64 reactions. In addition, the decay analysis of compound nuclei formed in the fusion of Ca2040+Ni2858,64 reactions is investigated by using DCM. The calculations are done for quadrupole (β2) deformed fragments having optimum orientations for hot configurations. The experimental data for evaporation residues lying within the wide range of center of mass energy (Ec.m.) of 6488 MeV is nicely addressed using the collective clusterization approach of the DCM. The comparative analysis of decay profiles of Cd*4898,104 is worked out by introducing angular momentum and temperature effects in the fragmentation potential and preformation factor.
