锕系核两准粒子激发态性质的研究

On the Properties of Two-quasi-particle Excitation Bands

根据最新发表的核能谱数据，计算锕系区核素的两准粒子转动惯量。简单叙述转动惯量的奇偶差，并详细分析了造成准粒子激发带转动惯量之间的关系Ｒｏｄ和Ｒｅｘｐ不符的物理机制，进而揭示堵塞效应的重要影响及ＢＣＳ理论的局限性。

The moment of inertia of quasi-particle are systematically calculated by use of the latest experimental data of rotational bands in Actinide region(A≥221). The odd--even differences of mo ment of inereia are analyzed,and the physical mechanism cauasing systemtial disorepancy betveen Real and Reep are also discussed in detail(here R refers to the relations among the xnoments of inertia of quasi--particle excitation bonds). Accordingly,the severe blocking effect and the lints of ho theroy are revealed.
