用一个球到多个球重叠到分离的几何形状来描述裂片相互以120°方向形变(品字型),相互沿一条直线的拉长三体形变,以及先非对称后对称的级联三分裂的形变过程。方便比较只用了一个形变参数。基于液滴模型计算了表面能和库仑能,加入了新生碎片之间的核势,局域壳效应的壳能,给出三种三分裂模式的形变势能比较。考虑热核的各种温度效应,计算了在有限温度下这三种模式的位垒穿透概率,给出高温核位垒高度下降甚至位垒消失,定性给出三分裂的最可能的裂变方式。
A ball-to-sphere overlapped to discrete geometry is used to describe that the lobes deform at 120 ° from one another (lettering), elongated three-body deforming along a straight line, and asymmetric post-symmetrical cascade triplets The deformation process. For comparison, only one deformation parameter is used. Based on the droplet model, the surface energy and Coulomb’s energy are calculated, and the shell potential of the local shell effect is obtained by adding the nuclear potential between the nascent debris and the comparison of the deformation potential energy of the three modes. Considering the various temperature effects of the thermonuclear, the barrier penetration probability of the three modes at finite temperature is calculated, and the highest possible fission mode of the triplet is given qualitatively given the decrease of the height of the high-temperature nucleus barrier or the disappearance of the barrier. .
