^（221）Ac核裂变及转动态的连续介质模型计算

Calculation of fission and rotating states of ￣(221)Acusing continuous medium model

应用密度可变连续介质模型计算了２２１Ａｃ核的裂变及高速转动态的某些宏观性质。结果表明裂变位垒高度与角动量的关系与实验数据符合较好。预言了鞍点态电荷的双重心分布。而对密度分布明显偏离均匀分布的大形变态计算位能曲面与转动液滴模型结果显著不同。

he continuous medium model with variable densities is used to calculate somemacroscopic properties of fission and fast rotating states of 221Ac. The calculated dependenceOf fission barrier on the angular momentum accords with the experimental data well. And thedouble mass center charge distributions at saddle point states are predicted. It is found thatbecause the densities may deviate from a uniform distribution,the calculated energy surfaceis different from that of the rotating liquid dtop model for the nuclear states with largedeformations.
