研究了氢原子单圈激发态自能的高阶束缚修正的渐近性质。我们评估了历史上有问题的A60系数的所有P态与主量子数n</=7和D态与n</=8，发现一个令人满意的表示的n依赖性的系数需要一个三参数的拟合。对于高能量对A60的贡献，我们找到了精确的公式。所获得的结果是相关的高精度激光光谱测量的解释。
We investigate the asymptotic properties of higher-order binding corrections to the one-loop self-energy of excited states in atomic hydrogen. We evaluate the historically problematic A60 coefficient for all P states with principal quantum numbers n</=7 and D states with n</=8 and find that a satisfactory representation of the n dependence of the coefficients requires a three-parameter fit. For the high-energy contribution to A60, we find exact formulas. The results obtained are relevant for the interpretation of high-precision laser spectroscopic measurements.
