研究$^{166}$Er中的低能偶极激发，通过核共振荧光提取相关磁偶极强度，发现$M1$强度分布分两组，认为分裂由自旋自由度而非核非轴对称性所致。

最近，通过核共振荧光对$^{166}$Er中的低能偶极激发进行了研究。提取了2.2至3.5MeV激发能量下与核剪刀模式相关的磁偶极强度，发现$M1$强度分布分为两组。我们将这种分裂解释为由自旋自由度引起，而非作者所提出的核非轴对称性导致。
英文摘要
Recently, low-energy dipole excitations in $^{166}$Er were investigated via nuclear resonance fluorescence [T. Shizuma {\it et al}, Phys. Rev. C {\bf 113}, 044325 (2026)]. The magnetic dipole strength associated with the nuclear scissors mode was extracted for excitation energies between 2.2 and 3.5 MeV. It was found that the $M1$ strength distribution is separated into two groups. We interpret this splitting as caused by the spin degrees of freedom instead of the nucleus nonaxiality suggested by authors.
