摘要
自发核裂变碎片的相对轨道矩 L 出现较大值的机制与裂变核在其破裂点的量子横向蠕动振动有关。这一机制假定裂变核在破裂成裂变碎片之前一直保持冷态。根据所考虑的机制，首次推导出了一个分析公式，用于估算裂变碎片的轨道动量平均值和角分布。所获得的结果是对理解核裂变的重要贡献，并对核反应堆中因裂变碎片发射的瞬时伽马射线传播而产生的热释放问题具有重要意义。
Estimating Orbital Momenta of Binary-Fission Fragments
The mechanism for the appearance of large values of the relative orbital momenta L of the fragments of spontaneous nuclear fission is shown to be associated with quantum transverse wriggling vibrations of the fissile nucleus at its rupture point. This mechanism assumes that the fissile nucleus remains cold up to its rupture into fission fragments. Based on the considered mechanism, an analytical formula was derived for the first time to estimate the average value of the orbital momentum and the angular distribution of fission fragments. The results obtained are an important contribution to the understanding of nuclear fission, and have important significance in problems of heat release in nuclear reactors arising from the propagation of instantaneous gamma rays emitted by fission fragments.
