本研究通过TPSM和PTR方法分析$^{74}$Br核的第三激发带，预测其为第二激发带的手性伙伴及基于第一激发带的摆动模式，揭示了新型手性摆动激发。
AI 中文摘要
利用三轴投影壳模型（TPSM）和粒子三轴转子（PTR）方法研究了$^{74}$Br核中高自旋带结构性质。已有研究表明，在$^{74}$Br中观测到的最低三条带具有手性摆动子的特征。第一激发带是晕带的手性伙伴，第二激发带是基于晕态的摆动带。我们利用TPSM和PTR计算量分析了第三激发带，揭示了该带的独特性质。预测该带是第二激发带的手性伙伴，同时也是基于第一激发带的摆动模式。
英文摘要
The properties of high-spin band structures in $^{74}$Br nucleus are investigated using the triaxial projected shell model (TPSM) and particle triaxial rotor (PTR) approaches. It has already been demonstrated that lowest three bands observed in $^{74}$Br have a characteristic feature of a chiral-wobbler. The first excited band is the chiral partner of the yrast band and the second excited band is the wobbling band based on the yrast state. We have analyzed the third excited band using the TPSM and PTR calculated quantities, and a unique character of this band is revealed. It is predicted that this band is the chiral partner of the second excited band, and is also a wobbling mode based on the first excited band.
