Hyperfine structure of the first rotational level in H, D and HD molecules and the deuteron quadrupole moment
Mariusz Puchalski, Jacek Komasa, Krzysztof Pachucki
We perform the four-body calculation of the hyperfine structure in the first rotational state of the H, D, and HD molecules and determine the accurate value for the d…
QED calculation of the fine structure in Li-like ions
Vladimir A. Yerokhin, Mariusz Puchalski, Krzysztof Pachucki
Large-scale {\em ab initio} QED calculations are performed for the -- fine-structure interval of Li-like ions with nuclear charges --. Improved t…
Second virial coefficients for helium-4 and helium-3 from accurate relativistic interaction potential
Paweł Czachorowski, Michał Przybytek, Michał Lesiuk +2
The second virial coefficient and the second acoustic virial coefficient for helium-4 and helium-3 are computed for a wide range of temperatures (0.5 - 1000K) using a highly accura…
QED calculation of ionization energies of states in helium
Vladimir A. Yerokhin, Vojtěch Patkóš, Mariusz Puchalski +1
Quantum electrodynamical (QED) calculations of ionization energies of the states are performed for the helium atom. We reproduce the previously known relativistic and QED…
Hyperfine structure in the HD molecule
Jacek Komasa, Mariusz Puchalski, Krzysztof Pachucki
We investigate interactions between the proton spin, the deuteron spin, and the orbital angular momentum in the electronic ground state of the HD molecule. These interactions lead…
