论文摘要
我们提出了一种有效的方法来根据裂变系统的驱动潜力来描述肌动剂的裂变损失收益率。考虑到原发性裂变片段在其基态下的性质，代表系统围绕分裂构型的势能并与碎片的产量紧密相关的驱动电位，可以从Skyrme能量密度与Weizsaecker-Skyrme质量模型一起从Skyrme能量密度的功能中明确而快速获得。热 - 中性诱导的裂变和一系列acttanidides的自发裂变（尤其是奇怪的荷里电荷分布中的奇特分布）的裂变裂缝电荷分布可以很好地再现。核动力变形和碎片的配对校正在电荷分布中起重要作用。
We propose an efficient approach to describe the fission-fragment charge yields for actinides based on the driving potential of fissioning system. Considering the properties of primary fission fragments at their ground states, the driving potential, which represents the potential energies of the system around scission configuration and closely relates to the yields of fragments, can be unambiguously and quickly obtained from the Skyrme energy-density functional together with the Weizsaecker-Skyrme mass model. The fission-fragment charge distributions for thermal-neutroninduced fission and spontaneous fission of a series of actinides, especially the odd-even staggering in charge distributions can be well reproduced. Nuclear dynamical deformations and pairing corrections of fragments play an important role in the charge distributions.
