The authors combine modern theoretical calculations with evaluated selected experimental
data to produce a comprehensive data resource of K-and Lx-ray transition and absorption …

The two-time Green's function method in quantum electrodynamics of high-Z few-electron
atoms is described in detail. This method provides a simple procedure for deriving formulas …

A model operator approach to calculations of the QED corrections to energy levels in
relativistic many-electron atomic systems is developed. The model Lamb shift operator is …

We perform ab initio QED calculations of energy levels for the n= 1 and n= 2 states of He-like
ions with the nuclear charge in the range Z= 12–100. The complete set of two-electron QED …

We present Fortran package QEDMOD for computing the model QED operator h QED that
can be used to account for the Lamb shift in accurate atomic-structure calculations. The …

The current status of bound state quantum electrodynamics calculations of transition
energies for few-electron ions is reviewed. Evaluation of one and two body QED correction …

A calculation of two-electron QED effects to all orders in the nuclear binding strength
parameter Z α is presented for the ground and n= 2 excited states of heliumlike ions. After …

The comparison between theory and experiment of the hyperfine structure splitting and the
electronic gj factor in heavy highly charged ions provides a unique testing ground for …

Using the SuperEBIT electron beam ion trap, we have measured the 2 s 1/2-2 p 1/2
transitions in U 88+ and U 89+. The measured value of 280.645±0.015 eV for Li-like U 89+ …

A possibility for a determination of the fine structure constant in experiments on the bound-
electron g-factor is examined. It is found that studying a specific difference of the g-factors of …
