Abstract

We calculate hard spin-independent three-loop radiative corrections to energy levels in muonium and positronium which are due to radiative corrections with polarization insertions in two-photon exchange diagrams. These corrections could be relevant for the new generation of precise 1S-2S and 2S-2P measurements in muonium and positronium.
