摘要: 发展反射不对称壳模型, 描述八极形变核. 哈密尔顿量包含了四极、 八极和十六极多极力，
单极和四极对力. 壳模型空间由八极形变轴对称Nilsson势加BCS的投影基矢构成. 理论模型再现了和解释了实验八极转动带的基本特性. 理论计算很好地再现了190, 194Hg的超形变转动带实验谱， 从而为八极超形变转动带的可能的实验证据提供了理论支持. The reflection asymmetric shell model approach has been developed for the description of octupole deformed nuclei. The Q· Q forces of quadrupole, octupole and hexadecapole as well as the monopole and quadrupole pairings are included in the Hamiltonian. The shell model space is spanned by a
selected set of the projected axial and octupole Nilsson + BSC basis. The general features of experimental octupole rotational bands can be reproduced and interpreted by the present model. The experimental superdeformed band states in 190, 194Hg are well reproduced by the present calculations, which provide theoretical support to the possible experimental evidence for the discovery of the octupole superdeformed rotational bands.
