摘要
本文讨论了一种三体裂变模型，其中第三个粒子（α粒子）是由于颈缩断裂处核势的非绝热变化而发射的。提出了α粒子能量和角分布的表达式。研究表明，裂变系统的自旋与α粒子轨道动量之间的相互作用（即末态中的自旋 - 轨道相互作用）导致了近期观测到的α粒子发射不对称性，这在形式上可与 T odd 关联联系起来。该模型预测不对称性对α粒子发射方向相对于裂变轴的角度无强烈依赖，这与实验数据相符。

备注
11 pages. The work was presented at the ISINN-9 (2001, Dubna, Russia) after a T odd triple correlation had been found in ternary fission. Now the model proposed in this work is of additional interest because it provides a possibility to describe a smooth angular dependence of triple correlation recently observed (see F. Goennenwein et al. PLB, 2007, V.652, P.13.)
