Biography

I have worked on the theoretical aspects of heavy ion reactions which in turn contribute immensely towards the understanding of nuclear reaction dynamics and related phenomenon at low energies. The Dynamical Cluster-decay Model (DCM) has been advanced to understand the decay paths of excited compound systems formed in heavy-ion reactions. The Preformed Cluster Model (PCM) is used to explore nuclear structure effects in ground state decay of a nucleus. Reaction dynamics and related aspects around Coulomb barrier, barrier modification effects, fission anisotropies, shell closure, isospin, incomplete fusion, and entrance channel have been explored.
