Hyperfine Structure of the Ground and First Excited States in Light Hydrogen-Like Atoms and High-Precision Tests of QED
Savely G. Karshenboim, Vladimir G. Ivanov
We consider hyperfine splitting of 1s and, in part, of 2s levels in light hydrogen-like atoms: hydrogen, deuterium, tritium, helium-3 ion, muonium and positronium. We discuss prese…
Hyperfine structure in hydrogen and helium ion
Savely G. Karshenboim, Vladimir G. Ivanov
QED theory of the hyperfine splitting of the and state in hydrogen isotopes and helium-3 ion is considered. We develop an accurate theory of a specific difference 8E_{HFS…
Hadronic Vacuum Polarization Contribution to the Muonium Hyperfine Splitting
Savely G. Karshenboim, Valery A. Shelyuto
We discuss hadronic effects in the muonium hyperfine structure and derive an expression for the hadronic contribution to the hfs interval in form of the one-dimensional integral of…
Two-Loop Polarization Contributions to Radiative-Recoil Corrections to Hyperfine Splitting in Muonium
Michael I. Eides, Howard Grotch, Valery A. Shelyuto
We calculate radiative-recoil corrections of order to hyperfine splitting in muonium generated by the diagrams with electron and muon polarization loops. These co…
One-Loop Electron Vertex in Yennie Gauge
Michael I. Eides, Valery A. Shelyuto
We derive a compact Yennie gauge representation for the off-shell one-loop electron-photon vertex, and discuss it properties. This expression is explicitly infrared finite, and it…
2s Hyperfine Structure in Hydrogen Atom and Helium-3 Ion
Savely G. Karshenboim
The usefulness of study of hyperfine splitting in the hydrogen atom is limited on a level of 10 ppm by our knowledge of the proton structure. One way to go beyond 10 ppm is to stud…
