Exploring the optimal way to produce Z=100-106 neutron-rich nuclei

The synthesis of neutron-rich heavy and superheavy nuclei is one of the key concerns of nuclear physics. There are only two ways to synthesize nuclei Z > 92: fusion evaporation reactions and multinucleon transfer reactions. To theoretically unify the description of fusion evaporation reactions and cross sections of multinucleon transfer reactions, the current model of the dinuclear system is further improved in the present work. The traditional statistical approach of calculating the chance of survival of compound nucleus in fusion evaporation reactions is replaced by using GEMINI++. The results reproduce well the experimental values and trends of the evaporation residue cross sections. Further, the best synthesis of Z = 100-106 even-Z nuclei is predicted using the improved model. The results show that radioactive projectile nuclei can be applied to fusion evaporation reactions for the synthesis of new neutron-rich nuclei.
