Cooperative laser‐electron‐nuclear processes: QED calculation of electron satellites spectra for multi‐charged ion in laser field

Abstract

AbstractA 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 Fe 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. © 2004 Wiley Periodicals, Inc.
