论文摘要
在这篇综述中，我们在严格的QED方法的框架内，以精确的一光谱和两光谱光谱进行了线轮廓的不对称性。使用各种示例对量子干扰效应的角相关性进行了详细分析。还考虑了与某些天体物理问题有关的非共振作用。特别是，使用ly $_α$ transition给出了Lorentz线曲线的非共振扩展的严格QED推导；文献中缺乏这样的QED派生。
In this review, we have investigated the asymmetry of the line profile in precision one- and two-photon spectroscopy of hydrogen and helium atoms within the framework of a rigorous QED approach. A detailed analysis of the angular correlations of the quantum interference effect has been carried out using various examples. Nonresonant effects are also considered in relation to some astrophysical problems. In particular, a rigorous QED derivation of the nonresonant extension for the Lorentz line profile is given using the Ly$_α$ transition as an example; such a QED derivation has been lacking in the literature.
