对“首次在$^{183}$ Au中观察到不同种类的多个横向摆动带”一文的评论[Phys. Rev. Lett. 125,132501(2015)]”
Comment on "First Observation of Multiple Transverse Wobbling Bands of Different Kinds in $^{183}$Au [Phys. Rev. Lett. 125, 132501 (2015)]"
摘要:
在[S. Nandi等人,物理修订版信函125,132501(2020)]在$^{183}$ Au中报告了两个横向摆动带。这一任务的关键实验证据是E2主导的摆动和正常带之间的连接跃迁,这是通过拟合测得的DCO比和偏振结果的支持。然而,根据对统计误差的分析,不确定性被显著低估。在合理的误差下,混合比不能被唯一地决定,并且M1占主导地位的字符不能被排除,这表明摆动分配仍然是有问题的。
英文摘要:
In [S. Nandi et al., Phys. Rev. Lett. 125, 132501 (2020)] two transverse wobbling bands were reported in $^{183}$Au. The critical experimental proof for this assignment is the E2 dominated linking transitions between the wobbling and normal bands, which are supported by fitting the measured DCO ratio and polarization results. However, the uncertainties are significantly underestimated according to an analysis on the statistical error. With reasonable error, the mixing ratios cannot be exclusively decided, and the M1 dominated character cannot be excluded, indicating that the wobbling assignment is still questionable.
