Nonadiabatic corrections to electric quadrupole transition rates in H
Krzysztof Pachucki, Michał Siłkowski
We derive formulas and perform calculations of nonadiabatic corrections to rates of electric quadrupole transitions in the hydrogen molecule. These corrections can be represented i…
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…
Born-Oppenheimer potentials for , , and states of the hydrogen molecule
Michał Siłkowski, Krzysztof Pachucki
We report on accurate variational calculations of the Born-Oppenheimer potential for excited states of the hydrogen molecule with , , and symmetries. The obtained potenti…
Accurate Born-Oppenheimer potentials for excited states of the hydrogen molecule
Michał Siłkowski, Magdalena Zientkiewicz, Krzysztof Pachucki
We report on highly accurate calculations of Born-Oppenheimer potentials for excited states of the hydrogen molecule for all possible combinations of singlet/triplet and…
Long-range asymptotics of exchange energy in the hydrogen molecule
Michał Siłkowski, Krzysztof Pachucki
The exchange energy, i.e. the splitting between gerade and ungerade states in the hydrogen molecule has proven very difficult in numerical calculation at large internuclear di…
Calculation of the molecular integrals with the range-separated correlation factor
Michał Silkowski, Michał Lesiuk, Robert Moszynski
Explicitly correlated quantum chemical calculations require calculations of five types of molecular integrals beyond the standard electron repulsion integrals. We present a novel s…
