论文摘要
在本文中，引入了新型的氦和氦气样原子系统的热校正。这些是绑定电子和核之间的热单光子交换以及由黑体辐射（BBR）诱导的结合电子之间的热量。所有派生都在严格的QED理论中给出。结果表明，这些热校正与$α$（良好的结构常数）的功率相同，与众所周知的BBR诱导的Stark偏移相同，但温度的行为不同。本文提出的数值结果使他们可以期望它们对现代实验的意义，并测试氦气中的基本相互作用。
In this paper the new type of thermal corrections for the helium and helium-like atomic systems are introduced. These are thermal one-photon exchange between the bound electrons and nucleus as well as between the bound electrons induced by the blackbody radiation (BBR). All the derivations are given within the rigorous QED theory. It is shown that these thermal corrections are the same order in powers of $α$ (fine structure constant) as the well-known BBR-induced Stark shift but the different behaviour in temperature. The numerical results presented in this paper make possible to expect their significance for modern experiments and testing the fundamental interactions in helium.
