Investigation of two-photon 2s -> 1s decay in one-electron and one-muon ions
V. A. Knyazeva, K. N. Lyashchenko, M. Zhang +2
We have studied the radiative decay of the 2s state of one-electron and one-muon ions, where the two-photon mechanism plays an important role. Due to the nuclear size corrections t…
Electron-loss-to-continuum cusp in collisions of U with N and Xe
P. -M. Hillenbrand, K. N. Lyashchenko, S. Hagmann +24
We study the electron-loss-to-continuum (ELC) cusp experimentally and theoretically by comparing the ionization of U projectiles in collisions with N and Xe targets, at…
Resonant elastic scattering of polarized electrons on H-like ions
D. M. Vasileva, K. N. Lyashchenko, A. B. Voitkiv +2
The polarization properties of the elastic electron scattering on H-like ions are investigated within the framework of the relativistic QED theory. The polarization properties are…
QED theory of elastic electron scattering on hydrogen-like ions involving formation and decay of autoionizing states
K. N. Lyashchenko, D. M. Vasileva, O. Yu. Andreev +1
We develop {\it ab initio} relativistic QED theory for elastic electron scattering on hydrogen-like highly charged ions for impact energies where, in addition to direct (Coulomb) s…
Effects of autoionization in electron loss from helium-like highly charged ions in collisions with photons and fast atomic particles
K. N. Lyashchenko, O. Yu. Andreev, A. B. Voitkiv
We study theoretically single electron loss from helium-like highly charged ions involving excitation and decay of autoionizing states of the ion. Electron loss is caused by either…
Calculation of differential cross section for dielectronic recombination with two-electron uranium
Konstantin N. Lyashchenko, Oleg Yu. Andreev
Calculation of the differential cross section for the dielectronic recombination with two-electron uranium within the framework of QED is presented. The polarization of the emitted…
