Virtual Delbrück scattering and the Lamb shift in light hydrogen-like atoms
Robert Szafron, Evgeny Yu. Korzinin, Valery A. Shelyuto +2
We return to the problem of evaluation of the light-by-light contribution to the energy levels of the hydrogen atom. We find an additional contribution directly related to the Delb…

The Lamb shift of the state in hydrogen: two-loop and three-loop contributions
Savely G. Karshenboim, Akira Ozawa, Valery A. Shelyuto +2
We consider the Lamb shift in hydrogen and helium ions, a quantity, required for an accurate determination of the Rydberg constant and the proton charge radius by means of hyd…
