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…
