Abstract
The multinucleon transfer reaction + is investigated within the framework of the dinuclear system (DNS) model combining gemini code. The DNS + gemini model is improved by including deformation degree of freedom. The shell effects on charge equilibration are investigated. Because of shell closure , the behavior of inverse charge equilibration is found, which results in remarkable effects on production of exotic nuclei around . The incident energy effects on production cross sections are investigated. Interestingly, it is found that the production yields of actinide neutron-rich nuclei strongly depend on the incident energy. However, for producing heavy neutron-rich nuclei around the incident energy effects are weak, in which the slight decrease of yields with increasing incident energy comes from damping of shell effects. Also, the contour map of isotope production cross sections are calculated at different incident energies. We predict that several unknown heavy neutron-rich nuclei around can be produced with cross sections at the order of to mb.
