论文摘要
评估了对氢和氢样离子的自发和诱导的过渡概率的热校正。找到的热校正由顶点Feynman图给出，其中顶点代表结合电子与核之间的热相互作用。在绝热的$ s $ -matrix形式主义的框架内，以完全相对论的方法对暴露于黑体辐射的原子（BBR）的界限过渡（BBR）进行热校正的所有推导。发现对过渡速率的顶点型辐射校正可以在氢原子中高度激发态的相应自发速率的水平上达到几％。对氢样原子系统的顶点型热校正进行了全面分析。
Thermal corrections to the one-photon spontaneous and induced transition probabilities for hydrogen and hydrogen-like ions are evaluated. The found thermal corrections are given by the vertex Feynman graph, where the vertex represents the thermal interaction between the bound electron and the nucleus. All derivations of thermal corrections to bound-bound transitions for an atom exposed to blackbody radiation (BBR) are made in a fully relativistic approach within the framework of the adiabatic $S$-matrix formalism. It is found that the vertex-type radiative corrections to the transition rates can be at the level of a few percent to corresponding spontaneous rates for highly excited states in the hydrogen atom. A comprehensive analysis of the vertex-type thermal corrections for hydrogen-like atomic systems is presented.
