Abstract
The multinucleon transfer reactions , and are investigated within the framework of dinuclear system (DNS) model with a decay model gemini. The calculated isotopic production cross sections in the reaction at can reproduce the experimental data well. Due to the subshell closures, the behavior of “inverse” quasifission process is found in the collisions of and . The reaction is more advantageous to produce neutron-rich isotopes with than and , because it has the lowest value of the potential energy that needed to overcome in the nucleon transfer process. Furthermore, the incident energy dependence of isotopic production cross sections in the reaction is studied. It is found that MeV is more suitable for producing new isotopes with , while MeV is the optimal incident energy for . The effect of incident energy on the interaction time is also investigated. The production cross sections of 88 unknown neutron-rich transuranium nuclei are predicted with the cross sections at the order of to .
