多核子转移反应已在双核系统模型中进行了研究。通过求解一组微观导出的主方程，将核子转移与相对运动能量和角动量的耗散耦合起来。模型中采用了势垒分布方法，以包含不同方向和动态效应的贡献。通过多核子转移反应产生碎片的可用数据可以通过近库仑势垒能量的反应模型来理解。研究发现，重中子富核的产生对入射能量的依赖程度较弱。然而，富质子核的产率随着入射能量的增加而增加。
The multinucleon transfer reaction has been investigated within the dinuclear system model. The nucleon transfer is coupled to the dissipation of relative motion energy and angular momentum by solving a set of microscopically derived master equations. A barrier distribution approach is implemented in the model in order to include the contributions of different orientations and dynamical effects. The available data of fragment production via multinucleon transfer reactions could be understood with the model for the reactions ofnear Coulomb barrier energies. It is found that the production of heavy neutron-rich nuclei weakly depends on the incident energy. However, the yields of proton-rich nuclei increase with the incident energy.
