Atomic structure calculations of helium with correlated exponential functions
Vladimir A. Yerokhin, Vojtech Patkos, Krzysztof Pachucki
The technique of quantum electrodynamics (QED) calculations of energy levels in the helium atom is reviewed. The calculations start with the solution of the Schrödinger equation an…
Radiative QED contribution to the helium Lamb shift
Vojtěch Patkóš, Vladimir A. Yerokhin, Krzysztof Pachucki
We present a derivation of the last unknown part of the contribution to the Lamb shift of a two-electron atom, induced by the radiative QED effects beyond the Bethe logarith…
QED calculation of ionization energies of states in helium
Vladimir A. Yerokhin, Vojtěch Patkóš, Mariusz Puchalski +1
Quantum electrodynamical (QED) calculations of ionization energies of the states are performed for the helium atom. We reproduce the previously known relativistic and QED…
Theory of the Lamb shift in hydrogen and light hydrogen-like ions
Vladimir A. Yerokhin, Krzysztof Pachucki, Vojtech Patkos
Theoretical calculations of the Lamb shift provide the basis required for the determination of the Rydberg constant from spectroscopic measurements in hydrogen. The recent high-pre…
