Calculation of quasi-degenerate energy levels of two-electron ions
O. Yu. Andreev, L. N. Labzowsky, G. Plunien +1
Accurate QED calculations of the interelectron interaction corrections for the , two-electron configurations for ions with nuclear charge numbe…
Dual kinetic balance approach to basis set expansions for the Dirac equation
V. M. Shabaev, I. I. Tupitsyn, V. A. Yerokhin +2
A new approach to finite basis sets for the Dirac equation is developed. It solves the problem of spurious states and, as a result, improves the convergence properties of basis set…
One- and two-photon resonant spectroscopy of hydrogen and anti-hydrogen atoms in external electric fields
L. Labzowsky, D. Solovyev, V. Sharipov +2
The resonant spectra of hydrogen and anti-hydrogen atoms in the presence of an external electric field are compared theoretically. It is shown that nonresonant corrections to the t…
Evaluation of the two-photon exchange diagrams for the electron configuration in Li-like ions
A. N. Artemyev, V. M. Shabaev, M. M. Sysak +4
We present ab initio calculations of the complete gauge-invariant set of two-photon exchange graphs for the electron configuration in Li-like ions. These calculat…
