Three-Loop Radiative-Recoil Corrections to Hyperfine Splitting Generated by One-Loop Fermion Factors
Michael I. Eides, Howard Grotch, Valery A. Shelyuto
We consider three-loop radiative-recoil corrections to hyperfine splitting in muonium generated by diagrams with one-loop radiative photon insertions both in the electron and muon…

Corrections of Order to -Levels of Helium
Michael I. Eides, Howard Grotch
Several new corrections of order to the energy levels of states in helium are obtained from radiative corrections to the Breit potential and from the polarization insert…
