评论:“自旋陷阱异构体在轻稀土区变形奇奇核中,接近 $N=98$”

Comment on "Spin-trap isomers in deformed, odd-odd nuclei in the light rare-earth region near $N=98$"

AI总结:

本文评论了关于 $^{162}$Tb 中自旋陷阱异构态的报道,指出其与现有数据不符,并重新解释为基态和分子污染物。

摘要:

R. Orford 等人 [Phys. Rev. C 102, 011303(R) (2020)] 基于潘宁阱质量测量,报道了 $^{162}$Tb 中一个位于 285.5(32) keV 的新异构 $(4^-)$ 态。这里我们表明,该结果与现有实验数据不相容。被识别为 $^{162}$Tb$^{m}$(质量过剩值为 $-65593.9(25)$ keV)的态实际上是 $1^-$ 基态。而被识别为 $^{162}$Tb 基态的态,很可能是一个具有相同质荷比的分子污染物。

英文摘要:

A new isomeric $(4^-)$ state at 285.5(32) keV in $^{162}$Tb was reported by R. Orford et al. [Phys. Rev. C 102, 011303(R) (2020)] based on a Penning-trap mass measurement. Here we show that this result is not compatible with existing experimental data. The state identified as $^{162}$Tb$^{m}$ with a mass-excess value of $-65593.9(25)$ keV is actually the $1^-$ ground state. The state identified as the ground state of $^{162}$Tb is most likely a molecular contaminant with the same mass-over-charge ratio.
