论文摘要
核性手性 - 差异（CHP）违规是在内在框架中同时破坏手性和反射对称性的，并通过反射 - 敏感的三轴粒子转子模型研究了。发现了针对理想的CHP违规系统的新对称性，并得出了电磁过渡的相应选择规则。提供了违反CHP的指纹，包括几乎退化的四重奏带和电磁过渡的选择规则。这些指纹通过服用2- $ j $ shell $ h_ {11/2} $和$ d_ {5/2} $的典型能量间距，以$ a = $ a = $ 130的nuclei检查这些指纹。
The nuclear Chirality-Parity (ChP) violation, a simultaneous breaking of chiral and reflection symmetries in the intrinsic frame, is investigated with a reflection-asymmetric triaxial particle rotor model. A new symmetry for an ideal ChP violation system is found and the corresponding selection rules of the electromagnetic transitions are derived. The fingerprints for the ChP violation including the nearly degenerate quartet bands and the selection rules of the electromagnetic transitions are provided. These fingerprints are examined for ChP quartet bands by taking a two-$j$ shell $h_{11/2}$ and $d_{5/2}$ with typical energy spacing for $A=$ 130 nuclei.
