论文摘要
本文讨论了在量子电动力学（QED）中自然产生的光子散射过程的线轮廓不对称。基于对氢原子进行的精确光谱实验，我们将注意力集中在两光子$ 1S-2S $过渡上。作为最精确确定的过渡频率之一，它是光学频率标准的关键支柱，用于确定基本物理常数，测试物理原理以及对新基本相互作用的搜索约束。在这项工作中获得的结果表明，有必要在精确的光谱实验中考虑自然线的不对称性。
The paper discusses the line profile asymmetry of the photon scattering process that arises naturally in quantum electrodynamics (QED). Based on precision spectroscopic experiments conducted on hydrogen atoms, we focus our attention on the two-photon $1s-2s$ transition. As one of the most precisely determined transition frequencies, it is a key pillar of optical frequency standards and is used in determining fundamental physical constants, testing physical principles, and searching constraints on new fundamental interactions. The results obtained in this work show the need to take into account the natural line profile asymmetry in precision spectroscopic experiments.
