| 英文摘要 | We used the cranking shell model to investigate the high-spin motions and structures of atomic nuclei. We focus the collective rotations of the A similar to 50, 80 and 110 nuclei. The A similar to 50 calculations show complicated g spectroscopy, which can have significant vibration effects. The A approximate to 80 N approximate to Z nuclei show rich shape coexistences with prolate and oblate rotational bands. The A approximate to 110 nuclei near the r-process path can have well-deformed oblate shapes that become yrast and more stable with increasing rotational frequency. As another important investigation, we used the configuration-constrained adiabatic method to calculate the multi-quasiparticle high-K states in the A similar to 130, 180 and superheavy regions. The calculations show significant shape polarizations due to quasi-particle excitations for soft nuclei, which should be considered in the investigations of high-K states. We predicted some important high-K isomers, e.g., the 8(-) isomers in the unstable nuclei of Dy-140 and Pb-188, which have been confirmed in experiments. In superheavy nuclei, our calculations show systematic existence of high-K states. The high-K excitations can increase the productions of synthesis and the survival probabilities of superheavy nuclei. |
