在双核系统模型的框架内研究了多核转移反应Xe124,136,144+U238, Xe136,144+Gd160, Xe136,144+Er170和。研究了电荷平衡对奇异核生成截面的影响。缺中子弹丸有利于产生跨靶缺中子核，而在质子吸收通道中产生富中子核的截面具有很大的优势。进一步研究了入口角动量对电荷平衡过程的影响。研究发现，在低角动量通道中，初始核的重构比外围碰撞更深刻。我们预测了几个富中子核在反应中的生成截面。发现许多未知的核可以在100兆的水平上产生。
The multinucleon transfer reactions Xe124,136,144+U238, Xe136,144+Gd160, Xe136,144+Er170, andare 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 projectileis favorable to produce transtarget neutron-deficient nuclei, whileshows 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, and. It is found that many unknown nuclei can be produced at the level ofto mb.
