Recent developments in frequency metrology and optical clocks have been based on
electronic transitions in atoms and singly charged ions as references. The control over all …

The research progresses on the investigations of atomic structure and collision dynamics
with highly charged ions based on the heavy ion storage rings and electron ion beam traps …

A most general density-matrix formalism is presented to investigate linear polarization of
characteristic lines following electron-impact excitation of atoms or ions with arbitrary …

We determined relative X-ray photon emission cross sections in Fe xvii ions that were mono-
energetically excited in an electron beam ion trap. Line formation for the 3s (3s− 2p) and 3d …

The Hitomi results for the Perseus cluster have shown that accurate atomic models are
essential to the success of X-ray spectroscopic missions and just as important as the store of …

The electron-impact excitation from the ground state to the autoionizing level 1 s 2 s 2 2 p
1/2 J= 1 and the subsequent nonradiative Auger decay 1 s 2 s 2 2 p 1/2 J= 1→ 1 s 2 2 s J …

Electron-impact excitation from the ground state to the excited energy level 2 p 3/2 of
hydrogenlike ions and subsequent Lyman-α 1 (2 p 3/2→ 1 s 1/2) radiative decay are …

We present a systematic measurement of the X-ray emission asymmetries in the K-shell
dielectronic, trielectronic, and quadruelectronic recombination of free electrons into highly …
