On the empirical dipole polarizability of He from spectroscopy of HeH
Nikesh S. Dattani, Mariusz Puchalski
Using a long-range polarization potential for HeH, we can obtain an empirical value for the Boltzmann constant with an order of magnitude greater precision than the p…
Electromagnetic moments of the bound system of charged particles
Albert Wienczek, Mariusz Puchalski, Krzysztof Pachucki
We consider a bound system of particles interacting via electromagnetic forces in an external electromagnetic field, including leading relativistic corrections. Each particle has a…
Quantum electrodynamics corrections to the fine splitting in Li
Mariusz Puchalski, Krzysztof Pachucki
We consider quantum electrodynamics (QED) corrections to the fine splitting in the Li atom. We derive complete formulas for the and $m\,α^7\,\l…
Ground state hyperfine splitting in the Be ion
Mariusz Puchalski, Krzysztof Pachucki
Relativistic and QED corrections are calculated for the hyperfine splitting (hfs) in the ground state of Be ions with an exact account for electronic correlati…
