Production of neutron-rich nuclei with Z=60–73 in reactions induced by Xe isotopes
AbstractThe multinucleon transfer reactions Xe124,136,144+U238, Xe136,144+Gd160, Xe136,144+Er170, and Xe136,144+W186 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 Xe124 is favorable to produce transtarget neutron-deficient nuclei, while Xe136,144 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 Xe136,144+Gd160, Xe136,144+Er170, and Xe136,144+W186. It is found that many unknown nuclei can be produced at the level of μb to mb.
