New Laser-Electron Nuclear Effects in the Nuclear γ Transition Spectra in Atomic and Molecular Systems

Abstract

A consistent QED perturbation theory approach is applied to calculation of the electron-nuclear γ-transition spectra of nucleus in the multicharged ion. The intensities of satellites are defined in the relativistic version of the energy approach (S-matrix formalism). As example, the nuclear transition in the isotope 5726 Fe with energy 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 multicharged atomic ion FeXIX are presented. The possible experiments for observation of the new effect in the thermalized plasma of O- like ions are discussed. Consistent, quantum approach to calculation of the electron-nuclear γ transition spectra (set of vibration-rotational satellites in molecule) of nucleus in molecule, which generalizes the well known Letokhov-Minogin model, is presented and based on the Dunham model potential approximation for potential curves of the diatomic molecules. Estimates are made for vibration-rotation-nuclear transition probabilities in a case of the emission and absorption spectrum of nucleus 127I (E (0)γ = 203 keV) in the molecule of H127I. Estimates of the vibration-nuclear transition probabilities in a case of the emission and absorption spectrum of nucleus 191Ir (E (0)γ = 82 keV) in the molecule of IrO4 and nucleus 188Os (E (0)γ = 155 keV) in the molecule of OsO4 are presented too.Keywordsatomsmoleculesspectralaser-electron nuclear effects
