论文摘要
提出了一种从一电子离子上的精确光谱数据中提取精细结构常数$α$的手段。我们表明，在边界电子$ g $因子和基态能量的适当加权差异中，可以有效地抑制核结构效应。预计该方法将通过现有或近乎未来的笔陷阱和X射线光谱技术提供独立的$α$，并通过数量级降低$α$的不确定性。
A means to extract the fine-structure constant $α$ from precision spectroscopic data on one-electron ions is presented. We show that in an appropriately weighted difference of the bound-electron $g$ factor and the ground state energy, nuclear structural effects can be effectively suppressed. This method is anticipated to deliver an independent value of $α$ via existing or near-future combined Penning trap and x-ray spectroscopic technology, and enables decreasing the uncertainty of $α$ by orders of magnitude.
