A New Benchmark for Quantum Electrodynamics in Atoms

March 28, 2025
Recently, the ALPHATRAP group around Sven Sturm in the division of Klaus Blaum at the Max Planck Institut für Kernphysik (MPIK) in Heidelberg measured the g factor of hydrogen-like tin ions on a precision level of 0.5 parts per billion. That is like measuring the distance Cologne-Frankfurt with a precision down to the thickness of a human hair This is a stringent test of QED for the simplest atomic system just like conventional hydrogen but with a much higher electric field experienced by the electron due to the charge of 50 protons inside the tin nucleus.
