Electron-nucleus Araki-Sucher correction in the hydrogen molecule isotopologues
Jacek Komasa
The quantum electrodynamic Araki-Sucher correction arising from the interaction between electrons and nuclei is calculated for rovibrational energy levels of the hydrogen molecule…
Integrals for relativistic nonadiabatic energies of H in exponential basis
Krzysztof Pachucki, Jacek Komasa
Accurate predictions for hydrogen molecular levels require the treatment of electrons and nuclei on an equal footing. While nonrelativistic theory has been effectively formulated t…
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…
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…
Nonrelativistic energy of tritium-containing hydrogen molecule isotopologues
Krzysztof Pachucki, Jacek Komasa
The nonrelativistic energy of low lying rovibrational levels of HT, DT, and \T\ is determined to an absolute accuracy of cm using the variational method wi…
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…
