Relativistic, QED, and finite nuclear mass corrections for low-lying states of Li and Be
Mariusz Puchalski, Krzysztof Pachucki
Accurate results for nonrelativistic energy, relativistic, QED, and finite nuclear mass corrections are obtained for , and states of the Li at…
Electric dipole rovibrational transitions in HD molecule
Krzysztof Pachucki, Jacek Komasa
The rovibrational electric dipole transitions in the ground electronic state of the HD molecule are studied. A simple, yet rigorous formula is derived for the transition rates in t…
Singular Hylleraas three-electron integrals
Krzysztof Pachucki, Mariusz Puchalski
Calculations of the leading quantum electrodynamics effects in few electron systems involve singular matrix elements of the inter-electronic distances of the form and $1/…
Ortho-para transition in molecular hydrogen
Krzysztof Pachucki, Jacek Komasa
The radiative ortho-para transition in the molecular hydrogen is studied. This highly forbidden transition is very sensitive to relativistic and subtle nonadiabatic effects. Our re…
