Antiprotonic atoms with nonperturbative inclusion of vacuum polarization and finite nuclear mass

V. Patkóš, K. Pachucki

We demonstrate that energy levels of excited states in a hydrogenic system consisting of an arbitrary nucleus and an antiproton can be calculated within the framework of nonrelativ…

Recoil corrections with finite nuclear size in hydrogenic systems

Krzysztof Pachucki, Vojtěch Patkóš, Vladimir A. Yerokhin

Formulas for the combined nuclear-recoil and finite-nuclear-size effects of order and are derived without any expansion in the nuclear charge radius , ma…

Two-body -state energies at order

Vojtěch Patkóš, Vladimir A. Yerokhin, Krzysztof Pachucki

We present an analytical calculation of the complete correction to energies of -levels of two-body systems consisting of the spin- or extended-size particles wit…

Accurate determination of Li nuclear magnetic moments

Krzysztof Pachucki, Vojtěch Patkóš, Vladimir A. Yerokhin

We report an accurate determination of the nuclear magnetic dipole moments of Li from the measured ratio of the nuclear and the electron -factors in atomic Li. The obtai…

Higher-order QED corrections to the hyperfine splitting in He

Vojtěch Patkóš, Vladimir A. Yerokhin, Krzysztof Pachucki

We present a calculation of the hyperfine splitting of the state in the He atom with inclusion of all QED effects up to , where is the Fermi splitting. Usi…

Nuclear polarizability effects in He hyperfine splitting

Vojtěch Patkóš, Vladimir A. Yerokhin, Krzysztof Pachucki

The nuclear polarizability effects in hyperfine splitting of light atomic systems are not well known. The only system for which they were previously calculated is the hydrogen atom…
