摘要
用试验粒子多次通过位垒方法计算重核在鞍点处的裂变速率,其结果明显低于以往所用首次通过位垒方法计算的值,更接近于断点处的裂变速率.给出了这两种量的正确描述,并进一步应用多次通过位垒的方法讨论了鞍点后势垒的非谐形式对于核裂变速率的影响.研究表明,鞍点后的动力学过程对于裂变速率的影响是不容忽视的.
The fission rate calculated by test particles multi-passing over saddle point is lower that the one calculated by test particles firstly passing over saddle point, and the appropriate description of this quantity is given in this paper. Further more, taking the effect of post-saddle mechanics into account, we investigate the influence of non-harmonic potential on nuclear fission rate in detail.
