Proton radii and two-photon exchange
Peter G. Blunden🇨🇦 · Ingo Sick🇨🇭
Abstract
We investigate the effect of two-photon exchange processes upon the rms- and Zemach radii extracted from electron-proton scattering. We find that the changes are small and do not help to explain the discrepancy between experimental and calculated HFS in the hydrogen atom.
