论文摘要
我们在激发态的量子电动力学效应的计算$ l> 1 $的任意两体系统高达$α^6 \，μ$订单中。只要强相互作用效果可忽略不计，获得的结果对于辐射原子是有效的。我们证明，对于具有$ l \ sim n $的圆形状态，有效的扩展参数为$ z \，α/n $，它扩展了派生公式对重离子的适用性。此外，包括高阶项的包含是可行的，这表明可以使用Muonic或抗机氢离子的激发态进行准确的测量，以确定基本常数并搜索尚未知道的远距离相互作用。
We perform a calculation of quantum electrodynamics effects in excited states with $l>1$ of arbitrary two-body systems up to $α^6\,μ$ order. The obtained results are valid for hadronic atoms, as long as the strong interaction effects are negligible. We demonstrate that for circular states with $l\sim n$, the effective expansion parameter is $Z\,α/n$, which extends the applicability of the derived formulas to heavy ions. Moreover, inclusion of higher-order terms is feasible, which indicates that accurate measurements of excited states of, for example, muonic or antiprotonic hydrogenic ions can be used to determine the fundamental constants and to search for the existence of yet unknown long-range interactions.
