Title:	Investigation of the electromagnetically induced transparency in era of cosmological hydrogen recombination
Abstract:	Investigations of the cosmic microwave background formation processes are one of the most actual problems in present time. In this paper we investigate hydrogen atom in an external photon fields from astrophysical point of view. Field characteristics are defined from conditions which are corresponded to the recombination era of universe. Approximation of three-level atom is used for the description of ätom - fields" interaction. It is found that the electromagnetically induced transparancy phenomena has a place in this case. Consideration of EIT phenomena makes it necessary to update astrophysical description of the processes of the cosmic microwave background formation and, in particular, Sobolev escape probability. Additional terms to the optical depth in definition of Sobolev escape probability on the level about $1\%$ are found.
