论文摘要
通过考虑Muonic $^{90} \ Mathrm {Zrm {Zr} $，$^{120} \ Mathrm {sn} $ {sn} $ and $Δ2p$^{90} \ Mathrm {sn} $和$^{208} $ union IN $Δ2p$^{90} \ a $^{208} \ mathrm {pb} $。核物理和原子物理学的最先进技术被汇集在一起，以便对核偏振能量转移的迄今为止最全面的计算。除非Muonic $^{208} \ Mathrm {pb} $的更微妙的情况，结果表明，主要的计算不确定性比理论和实验之间的持续差异要小得多。我们得出的结论是，对异常的分辨率可能源于精制的QED校正，甚至是其他一些以前未指定的贡献。
A long-standing problem of fine-structure anomalies in muonic atoms is revisited by considering the $Δ2p$ splitting in muonic $^{90}\mathrm{Zr}$, $^{120}\mathrm{Sn}$ and $^{208}\mathrm{Pb}$ and the $Δ3p$ splitting in muonic $^{208}\mathrm{Pb}$. State-of-the-art techniques from both nuclear and atomic physics are brought together in order to perform the most comprehensive to date calculations of nuclear-polarization energy shifts. Barring the more subtle case of muonic $^{208}\mathrm{Pb}$, the results suggest that the dominant calculation uncertainty is much smaller than the persisting discrepancies between theory and experiment. We conclude that the resolution to the anomalies is likely to be rooted in refined QED corrections or even some other previously unaccounted-for contributions.
