Doppler-shifted X-ray Spectroscopy of Nonradiative Electron Capture in Relativistic Collisions of Xe54+ Ions with Kr and Xe Atoms

Bian Yang, Deyang Yu, Konstantin N. Lyashchenko +13

We present an angular-resolved Doppler spectroscopy study of nonradiative electron capture in relativistic collisions of bare Xe54+ ions with Kr and Xe gas targets at the HIRFL-CSR…

Angular distribution of Kα x rays following nonradiative double electron capture in relativistic collisions of Xe54+ ions with Kr and Xe atoms

Bian Yang, Deyang Yu, Konstantin N. Lyashchenko +13

We present experimental study of nonradiative double electron capture processes in collisions of 95 and 146 MeV/u bare xenon ions with krypton and xenon gaseous atoms at the HIRFL-…

Electron polarization in the resonant inelastic scattering on hydrogen-like ions

D. M. Vasileva, K. N. Lyashchenko, O. Yu. Andreev

We investigate the polarization of the electron beam acquired during the inelastic resonant scattering on hydrogen-like ions initially being in the ground state. The formation and…

Electron-positron pair production in bound-bound muon transitions

Oleg Yu. Andreev, Deyang Yu, Konstantin N. Lyashchenko +1

We explored a distinct mechanism for matter creation via electron-positron pair production during bound-bound transitions in the deexcitation of one-muon ions. For ions with nuclea…

Photon Angular Distribution in Two-Photon Electron Capture by H-Like Uranium

K. N. Lyashchenko, O. Yu. Andreev, D. Yu

We present a comprehensive study of the angular distribution of photons emitted during the resonant two-photon electron capture by H-like uranium ions. Focusing on the energies of…
