Vertex-type thermal correction to the one-photon transition rates

摘要: Thermal corrections to the one-photon spontaneous and induced transition probabilities for hydrogen hydrogen-like ions are evaluated. The found thermal given by vertex Feynman graph, where represents interaction between bound electron nucleus. All derivations of bound-bound transitions an atom exposed blackbody radiation (BBR) made in a fully relativistic approach within framework adiabatic $S$-matrix formalism. It is that vertex-type radiative rates can be at level few percent corresponding highly excited states atom. A comprehensive analysis atomic systems presented.
