Abstract

We review recent experiments on HD⁺ spectroscopy. The reduced proton-deuteron mass to electron mass ratio, \({{\mu }_{{pd}}}{\text{/}}{{m}_{e}}\), is inferred from the comparison of theory and experiment. Theoretical issues related to the calculations of the spin structure, which are currently the main limiting factor of theoretical accuracy, are discussed.

氢分子离子的精密光谱：理论与实验现状

摘要

我们回顾了最近关于 HD ⁺光谱学的实验。降低的质子-氘核质量与电子质量比\({{\mu }_{{pd}}}{\text{/}}{{m}_{e}}\)是从比较理论和实验。讨论了与自旋结构计算相关的理论问题，这些问题目前是理论精度的主要限制因素。
