Enhanced polarization transfer to the characteristic x-ray lines near the nonlinear Cooper minimum of two-photon ionization
J. Hofbrucker, A. V. Volotka, J. Szlachetko +1
It has been shown that for nonlinear atomic ionization, transfer of the degree of circular polarization from incident to fluorescence light is maximum at the Cooper minimum (see Ph…
Rayleigh scattering of a linearly polarized light: scenario of the complete experiment
A. V. Volotka, A. Surzhykov, S. Fritzsche
The process of the elastic scattering of photons on atoms, known as the Rayleigh scattering, is investigated. Expressing the scattering observables in terms of the electric and mag…
Fluorescence polarization as a precise tool for understanding nonsequential many-photon ionization
J. Hofbrucker, A. V. Volotka, S. Fritzsche
Nonsequential two-photon ionization of inner-shell subshell of neutral atoms by circularly polarized light is investigated. Detection of subsequent fluorescence as a signature…
Ground-state hyperfine splitting of B-like ions in high-Z region
D. A. Glazov, A. V. Volotka, O. V. Andreev +5
The hyperfine splitting of the ground state of selected B-like ions within the range of nuclear charge numbers is investigated in detail. The rigorous QED approach togeth…
Maximum Elliptical Dichroism in Atomic Two-Photon Ionization
J. Hofbrucker, A. V. Volotka, S. Fritzsche
Elliptical dichroism is known in atomic photoionization as the difference in the photoelectron angular distributions produced in nonlinear ionization of atoms by left- and right-ha…
Angle-resolved x-ray spectroscopic scheme to determine overlapping hyperfine splittings in highly charged helium-like ions
Z. W. Wu, A. V. Volotka, A. Surzhykov +1
An angle-resolved x-ray spectroscopic scheme is presented for determining the hyperfine splitting of highly charged ions. For helium-like ions, in particular, we propose to measure…
