氢分子基态的前导级QED效应

Leading-order QED effects in the ground electronic state of molecular hydrogen

Michał Siłkowski, Jacek Komasa, Mariusz Puchalski, Krzysztof Pachucki

摘要:

我们对氢分子基态的首阶QED修正进行了高精度的计算。数值结果得到的网格的核间距$R=0-10$ au的相对精度约为$10^{-8}$。以往QED结果的主要数值不确定性[K. Piszczatowski等人,JCTC $\textbf{5}$,3039(2009)]已被删除。然而,在1.9 $σ$水平下与HD测量值的差异仍然存在。

英文摘要:

We perform highly accurate calculations of the leading order QED correction to the ground electronic state of molecular hydrogen. Numerical results are obtained for a grid of the internuclear distances $R=0-10$ au with the relative precision of about $10^{-8}$. The major numerical uncertainty of previous QED results [K. Piszczatowski et al., JCTC $\textbf{5}$, 3039 (2009)] has been eliminated. Nevertheless, the discrepancy with measurements in HD at the level of 1.9 $σ$ persists.
