Deformation and Internal Symmetry of Rapidiy Nuclei

在该研究项目中，研究了原子核结构研究中最重要的课题--快速旋转静子的核变形和内部对称性。在形变原子核中，为了描述自转运动，引入了一个内部坐标系。内部统计具有轴对称性和点群对称性等对称性，这是转动带的特征。研究了签名的对称性，解释了S带内的签名反转现象。在扭动运动和振动运动强耦合的情况下，研究了Delta-Sotor的经典量子化背景下的Delta自由度。

In the research project, the most inportant subject for study of Nuclear structure, the nuclear deformation and intrernal symmetry of rapidly rotating statis are investigated. In deformed nuclei, an internal frame of coordinate system is introduced in orderto describe rotational motion. The internal statis have symmetries such as axial symmetry and point group symmety, which characterize the rotational bands. The symmety of signature is studied to interpret the signature inversion found in S-band. The delta-degree of freedom is studied in the context of classical guantrzation for delta-soft sotor, in which woblling motion and delta-vibrational motion are strongly conpled.
