Reflection Asymmetric Shell Model for Octupole Nuclei

    Corresponding author: CHEN Yong-shou

  • 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.
    Abstract: 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.
