Radiative corrections of the order for rotational states of two-body systems
Vojtěch Patkóš, Krzysztof Pachucki
The analytical calculation of the complete one-loop radiative correction to energies of two-body systems with the angular momenta , consisting of a pointlike par…
Hyperfine splitting in Li
Krzysztof Pachucki, Vojtěch Patkóš, Vladimir A. Yerokhin
We present a detailed derivation of the QED effects of order to the hyperfine structure (hfs) of the states of helium-like ions and perform numerical calculations fo…
Quantum electrodynamics of two-body systems with arbitrary masses
Jacek Zatorski, Vojtěch Patkóš, Krzysztof Pachucki
We perform a calculation of quantum electrodynamics effects in excited states with of arbitrary two-body systems up to order. The obtained results are valid for hadr…
Relativistic Bethe logarithm for triplet states of helium-like ions
Vladimir A. Yerokhin, Vojtěch Patkóš, Krzysztof Pachucki
We report a calculation of relativistic corrections of order to the Bethe logarithm for the and states of helium-like ions. The calculation is required for imp…
QED calculations of energy levels of helium-like ions with
Vladimir A. Yerokhin, Vojtěch Patkóš, Krzysztof Pachucki
A calculation of two-electron QED effects to all orders in the nuclear binding strength parameter is presented for the ground and excited states of helium-like ions. A…
Higher-order recoil corrections for singlet states of the helium atom
V. Patkos, V. A. Yerokhin, K. Pachucki
We investigate the finite nuclear mass corrections in the helium atom in order to resolve a significant disagreement between the and transition isotope…
