Relativistic calculations of the non-resonant two-photon ionization of neutral atoms
Jiri Hofbrucker, Andrey V. Volotka, Stephan Fritzsche
The non-resonant two-photon one-electron ionization of neutral atoms is studied theoretically in the framework of relativistic second-order perturbation theory and independent part…
Level sequence and splitting identification of closely-spaced energy levels by angle-resolved analysis of the fluorescence light
Z. W. Wu, A. V. Volotka, A. Surzhykov +2
The angular distribution and linear polarization of the fluorescence light following the resonant photoexcitation is investigated within the framework of the density matrix and sec…
Many-electron effects on the x-ray Rayleigh scattering by highly charged He-like ions
A. V. Volotka, V. A. Yerokhin, A. Surzhykov +2
The Rayleigh scattering of x-rays by many-electron highly charged ions is studied theoretically. The many-electron perturbation theory, based on a rigorous quantum electrodynamics…
