Relativistic treatment of diamagnetic susceptibility of helium
Mariusz Puchalski, Michał Lesiuk, Bogumił Jeziorski
We report theoretical calculations of the diamagnetic susceptibility, , of helium atom. We determined the complete relativistic correction to of the order of , wher…
Leading-order QED effects in the ground electronic state of molecular hydrogen
Michał Siłkowski, Jacek Komasa, Mariusz Puchalski +1
We perform highly accurate calculations of the leading order QED correction to the ground electronic state of molecular hydrogen. Numerical results are obtained for a grid of the i…
QED theory of the nuclear magnetic shielding in H and He
Dominik Wehrli, Mariusz Puchalski, Krzysztof Pachucki
The derivation of leading quantum electrodynamic corrections to the nuclear magnetic shielding in light hydrogen- and helium-like atomic systems is described in detail. The present…
Nuclear magnetic shielding in HD and HT
Mariusz Puchalski, Jacek Komasa, Anna Spyszkiewicz +1
We perform a calculation of the nuclear magnetic shielding in HD and HT molecules, with complete and perturbative accounts for nuclear masses. From the difference in shielding, we…
QED effects on the nuclear magnetic shielding of He
Dominik Wehrli, Anna Spyszkiewicz-Kaczmarek, Mariusz Puchalski +1
The leading quantum electrodynamic corrections to the nuclear magnetic shielding in one- and two-electron atomic systems are obtained in a complete form, and the shielding constant…
Fine and hyperfine splitting of the low-lying states of Be
Mariusz Puchalski, Jacek Komasa, Krzysztof Pachucki
We perform accurate calculations of energy levels as well as fine and hyperfine splittings of the lowest , , , and excited states…
