Abstract：
The passing probability of nuclear fusion and the fission rate at the saddle point is calculated by an improved scheme with test particle muti passing over the saddle point,where a strong back streaming effect around the saddle is found and considered.It is also found that the back streaming becomes stronger if the post saddle barrier gets smoother.Fusion probability and fission rate,which are simulated usually via test particle first passing over the saddle model,are decreased by the back streaming effect.
