| Research Abstract |
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.
