锕系核集体运动的负宇称态

Negative Parity States of Collective Motion in Actinide Nuclei

从锕系区４０多个核的正负宇称态的实验数据，如激发能、Ｊπ、电偶极跃迁等，得到一系列与核结构有关的物理量，如宇称劈裂能级差δＥＩ，正负宇称带的第一和第二类转动惯量Ｊ（１）和Ｊ（２）及第一负宇称态的电偶极跃迁强度比等，以及它们与角动量Ｉ或转动角频率ω的动力学和核子数Ａ的系统行为，从而为研究锕系核负宇称态的产生机制及动力学特点提供了信息．

The physical quantities such as energy difference δ E_I of the positive and negative parity states of the same spin, moment of inertia J￣(1) and J￣(2), electric dipole transition branching ratios of first negative parity states and the relations between them and angular momentum or rotational frequency ω and mass number A are obtained from the experimental data. So the intrinsic structure and dynamics of negative parity states can be deduced.
