Abstract

A rigorous quantum electrodynamics theory of the multiphoton decay of excited states in a hydrogen atom is presented. The ``two-photon'' approximation is formulated which is limited by the one- and two-photon transitions including cascade transitions with two-photon links. This may be helpful for the strict description of the recombination process in a hydrogen atom and, in principle, for the history of hydrogen recombination in the early universe.
