论文摘要
最近通过将电子氢($ h $)和muonic氢($μh$)原子的结果之间的四个标准偏差差异降低到$ 3.3 $ value之间的四个标准偏差差异来解决“质子半径拼图”。从实验中提取的质子的根平方半径($ r_p $)的价值,即测量单光子$ 2S-4P $过渡和氢气转移的质量,现在是0.8335(95)$ FM,与Muonic Hydrogogen实验型($ 0.844087(39)(39)(39)(39),这是很好的一致。即便如此,这些值也显着偏离尾巴值,该值使用各种光谱线的结果确定为平均值,包括氢原子中的两光子转变。通过考虑到单光子散射过程中干扰效应的影响来实现质子半径拼图的解。在原子频率测量中的干扰效应的重要性为基于两光谱光谱的实验研究带来了动力,并具有类似的彻底性。这里显示的是,在氢原子中干扰两光子$ 2S-ND $过渡的途径在确定质子电荷半径和rydberg常数方面也很重要。
The "proton radius puzzle" was recently solved by reducing the four-standard deviation discrepancy between the results for electronic hydrogen ($H$) and muonic hydrogen ($μH$) atoms to $3.3$ value. The value of the root-mean-square radius of the proton ($r_p$), extracted from experiments on measuring the one-photon $2s-4p$ transition and the Lamb shift in hydrogen, is now $0.8335(95)$ fm, that is in good agreement with the muonic hydrogen experiments, $0.84087(39)$ fm. Even so, these values deviate significantly from the CODATA value, which is determined as the average using the results for various spectral lines including two-photon transitions in the hydrogen atom. The solution of the proton radius puzzle was realized by taking into account the influence of interference effect in one-photon scattering processes. The importance of interfering effects in atomic frequencies measurements gives an impetus to the study of experiments based on two-photon spectroscopy with the suchlike thoroughness. It is shown here that the effect of interfering pathways for two-photon $2s-nd$ transitions in a hydrogen atom is also significant in determining the proton charge radius and Rydberg constant.
