Description
Summary:The investigation of Si-induced isotopic chain of reactions 28,30Si+12C populating compound nuclei (CN) 40,42Ca*, respectively, with Z=20 shell closure and neutron number is gradually moving away from N = 20 neutron shell closure, has been performed within clusterisation approach of dynamical cluster-decay model (DCM) using deformed configurations effects included up to quadruple deformations (β2i) for two nuclei having optimum orientations θiopt.. The experimental fusion cross-sections of 30Si+12C is reproduced using DCM and further, the fusion cross-sections are predicted for other isotope of Si beam on 12C at lower energies to investigate the fusion process in terms of hindrance as function of neutron number. It is observed that the quantum tunneling of the fragments is less hindered in case of 40Ca*, as compared to 42Ca*, at the lower values of E c.m. i.e. having less barrier modification ΔVB in the case of former.
