Research Abstract

1. The quantized self-consistent collective coordinate (SCC) method, which is one of the methods to take into account the coupling effects between various collective modes in nuclei, especially the coupling effects between the collective and non-collective degrees of freedom, has been applied to various kinds of nuclides and the usefulness of the method, particularly of the Dyson type SCC method, has been confirmed. By using this method, the mechanism of the "phase transition" from spherical to deformed nuclei is being clarified. We have elucidated that the phase transition in the Sm isotopes comes mainly from the coupling effects between the collective quadruple vibrational mode and non-collective quadruple (or hexsa-deca-pole) modes. Consequently, it has been clarified that the SCC method is quite powerful to microscopically describe the nuclear collective motions.
2. Using the SCC method we can investigate the stability of nuclear collective motions and their separability from the no … More n-collective motions. Applying the SCC method to some. simple models, we have studied the relation between the stability of the nuclear collective motions and their stochastic or chaotic properties. Thereby we have had a clue for investigation of chaotic irregular motions in quantum many-particle systems.
3. A new method to study the coupling effect between collective motion and single-particle motion in rapidly-rotating (high spin) nuclei. Using this method, we have clarified how the dynamical gamma-deformation in nuclear high spin states varies as the nuclear spin increases.
4. The microscopic structure of the scissors modes has been clarified by calculating the collectivity of the M1 transitions from these states. And we have studied the characteristics of the E2 and M1 transitions in strongly deformed nuclei.
5. A method to precisely evaluate the coupling effects between collective rotational motion and single-particle motion. Using this we have theoretically investigated the band-Crossing phenomena, and compared the results with experiment. Less
