Spontaneously Broken Rotational Symmetry in Nuclear Structure: Some New Theoretical Aspects

  • The Reflection Asymmetric Shell Model has been generated to include the triaxial degree of freedom. The signature inversion and chiral and wobbling band structures can be described by the present model as results of some nuclei having intrinsic mean fields with spontaneously broken rotational symmetry. As a application of the theory, the triaxial rotation, a fundamental question in nuclear structure, has been investigated by examining the signature inversion and chirality phenomena in nuclei. The signature inversion phenomenon is interpreted as the change of the dynamic cranking axis in triaxially deformed nuclei. An other goal is to provide a new understanding of the nature of the doublet bands in 134Pr.

Abstract: The Reflection Asymmetric Shell Model has been generated to include the triaxial degree of freedom. The signature inversion and chiral and wobbling band structures can be described by the present model as results of some nuclei having intrinsic mean fields with spontaneously broken rotational symmetry. As a application of the theory, the triaxial rotation, a fundamental question in nuclear structure, has been investigated by examining the signature inversion and chirality phenomena in nuclei. The signature inversion phenomenon is interpreted as the change of the dynamic cranking axis in triaxially deformed nuclei. An other goal is to provide a new understanding of the nature of the doublet bands in 134Pr.
