通过引入与激发相关的液滴模型，改进了裂变点模型，计算了中子诱发锕系核裂变的质量分布。激发能效应影响轻碎片和重碎片的变形。改进后的裂变点模型在计算入射中子能量高达99.5 MeV的中子诱发典型锕系元素裂变的中子发射前质量分布的精度方面有了显著的提高。该理论框架保证了改进的裂变点模型适用于计算裂变碎片质量分布，为裂变物理研究、核裂变工程设计和核嬗变系统设计提供了指导。
The scission point model is improved by considering the excitation-dependent liquid drop model to calculate mass distributions for neutron-induced actinide nuclei fission. Excitation energy effects influence the deformations of light and heavy fragments. The improved scission point model shows a significant advance with regard to accuracy for calculating pre-neutron-emission mass distributions of neutron-induced typical actinide fission with incident-neutron-energies up to 99.5 MeV. The theoretical frame assures that the improved scission point model is suitable for evaluating the fission fragment mass distributions, which will provide guidance for studying fission physics and designing nuclear fission engineering and nuclear transmutation systems.
