A $\sim$ 200质量区域中的Fission势垒高度

Fission barriers heights in A$\sim$ 200 mass region

K. Mahata

摘要:

在A $\sim$ 200质量区,采用一致的裂变势垒和能级密度描述,对$p$和$α$诱发裂变反应进行了统计模型分析。考虑了具有激发能的壳修正的连续阻尼。提取的裂变势垒同意最近的微观-宏观模型。在鞍点的壳修正被发现是不显着的。

英文摘要:

Statistical model analysis has been carried out for $p$ and $α$ induced fission reactions using a consistent description for fission barrier and level density in A $\sim$ 200 mass region. A continuous damping of shell correction with excitation energy have been considered. Extracted fission barriers agree well with the recent microscopic-macroscopic model. The shell corrections at the saddle point were found to be not significant.
