Description
Summary:In order to study the influence of neutron excess of projectile on multinucleon transfer process, the reaction systems Ni64+208Pb and Xe136+208Pb are investigated within the dinuclear system (DNS) model, where dynamic deformation as well as temperature are taken into account consistently on the potential energy surface of the system. The calculated transfer cross sections can well reproduce the experimental data. By comparing the obtained results of the two reaction systems involved above, we found that the fragment distribution of the transfer reaction induced by Xe136 (N/Z=1.51) appears to extend out to larger neutron numbers than that induced by Ni64 (N/Z=1.28). It is found that the radioactive projectiles Xe140 (N/Z=1.59) and Xe144 (N/Z=1.67) with much larger neutron excess in comparison to the stable beam Xe136 (N/Z=1.51) are favorable to produce neutron-rich nuclei with lighter and slightly more charged than the original Pb208 target.
