摘要

where σc is the effective capture cross section for the transition of the colliding nuclei over the entrance Coulomob arrier, Wsur is the survival probability of the compound nucleus. In the DNS model, the compound nucleus is reached by a series of transfers of nuclcons from the light nucleus to the heavy one. Thc dynamics of the DNS is considered as a diffusion process in the mass asymmetry degree of freedom η=(A1 - A2)/(A1 + A2) (A1 and A2 are the mass numbers of the DNS nuclei), PCN is the complete fusion probability, here it is calculated by solving the Master equation numcrically[2]. The fusion barrier Bfus in η supplies a hindrance for fusion.
