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

The multinucleon transfer reactions 124,136,144Xe + 238U, 136,144Xe + 160Gd, 136,144Xe + 170Er, and 136,144Xe + 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 136,144Xe 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 136,144Xe + 160Gd, 136,144Xe + 170Er, and 136,144Xe + 186W. It is found that many unknown nuclei can be produced at the level of μb to mb. [ABSTRACT FROM AUTHOR]
