论文摘要
核裂变会产生碎片，其旋转通过角动量保护与相对角运动耦合。可以通过直接的微型典型采样或通过采样相关的正常旋转模式来轻易获得此类自旋的集合。在各种三维场景中说明了自旋旋转开头的产生分布，并证明了如何通过对Scission几何形状的不同假设来很好地复制最近的相互冲突模型计算。
Nuclear fission produces fragments whose spins are coupled to the relative angular motion via angular momentum conservation. It is shown how ensembles of such spins can readily be obtained by either direct microcanonical sampling or by sampling of the associated normal modes of rotation. The resulting distribution of the spin-spin opening angle is illustrated in various three- and two- dimensional scenarios and it is demonstrated how recent mutually conflicting model calculations can be well reproduced with different assumptions about the scission geometry.
