Production of neutron-rich nuclei with Z =60 -73 in reactions induced by Xe isotopes

The multinucleon transfer reactions ^124,136,144Xe +²³⁸U , ^Xe,144₁₃₆+¹⁶⁰Gd , ^Xe,144₁₃₆+¹⁷⁰Er , and ^Xe,144₁₃₆+¹⁸⁶W are investigated within the framework of the dinuclear system model. The charge equilibration effects on the production cross sections of exotic nuclei are studied. The neutron-deficient projectile ¹²⁴Xe is favorable to produce transtarget neutron-deficient nuclei, while ^Xe,144₁₃₆ shows great advantages of cross sections for producing neutron-rich nuclei in the proton pick-up channel. Furthermore, the influence of entrance angular momentum on the charge equilibration process is investigated. It is found that in a low angular momentum channel the more profound reconstruction of initial nuclei is noticed rather than peripheral collisions. We predict the production cross sections of several neutron-rich nuclei in the reactions ^Xe,144₁₃₆+¹⁶⁰Gd , ^Xe,144₁₃₆+¹⁷⁰Er , and ^Xe,144₁₃₆+¹⁸⁶W . It is found that many unknown nuclei can be produced at the level of μ b to mb.
