Abstrakt:	A consistent quantum electrodynamics (QED) perturbation theory approach is developed and applied to calculation of the electron-nuclear γ-transition spectra of nucleus in the multi-charged ion. The intensities of satellites are defined in the relativistic version of the energy approach (S-matrix formalism). Decay and excitation probabilities are linked with an imaginary part of the energy of the ‘‘nuclei nucleons-electron shells-field’’ system. As an example, the nuclear transition in the isotope 5726Fe with an energy of 14.41 keV is considered. The results of the relativistic calculation for the electron-nuclear γ-transition spectra (set of electron satellites) of the nucleus in a multi-charged atomic ion FeXIX are presented and compared with the corresponding nonrelativistic estimates.
