| Abstract | The advent of heavy ion reactions has facilitated to investigate the production and reaction mechanism of new heavy and superheavy nuclei via fusion reactions. Theoretically, models are advanced, e.g., by Gupta and collaborators for both the spontaneous (T=0; cluster radioactivity, the ground-state decay phenomenon) and excited (T>0) compound nuclei (CN) decays, namely the Preformed cluster model (PCM) and the Dynamical cluster-decay model (DCM) [1], respectively. In both cases, nuclear structure effects come in to play through the so-called preformation factor P0 (the spectroscopic factor) of decay products. Using the DCM with various different nuclear interaction potentials, we have studied the hot fusion reactions for coplanar (Φ = 0) and non-coplanar (Φ ̸=0) nuclei. The DCM, based on the well-known quantum mechanical fragmentation theory of fission, heavy-ion reactions and exotic cluster radioactivity, successful for light to superheavy nuclei, defines the compound nucleus decay/ formation cross section for each fragmentation (A1, A2), for l partial waves, as |
