Entrance-channel effects in the dynamical cluster-decay model for the decay of hot and rotating compound nucleus 48Cr at E*CN≈60 MeV

The entrance-channel effects in the decay of hot and rotating compound nucleus Cr-48*, formed in symmetric Mg-21 + Mg-24 and asymmetric Ar-36 + C-12 reactions, are studied as collective clusterization process, for emissions of both the light particles (LPs) as well as the intermediate mass fragments (IMFs), with in the dynamical cluster-decay model (DCM). We find that the little differences observed in the decay of equilibrated compound nucleus Cr-48*, formed in the two entrance channels with about the same excitation energy, are not in variance with the Bohr's independence hypothesis. In other words, the present study confirms the entrance-channel independence of the decay of compound nucleus Cr-48* formed due to different target-projectile combinations with similar excitation energies. The collective clusterization process is shown to contain the complete structure of the measured fragment cross sections as well as average total kinetic energies.
