Quantum electrodynamics, the archetypical theory of electromagnetic interactions, describes the behaviour of charged particles and photons using quantum field theory. Measuring the g factor of a bound electron in a hydrogen-like tin ion (118Sn49+) provides one of the most stringent tests so far of quantum electrodynamics in strong electric fields. Measuring the g factor of a single electron bound to a tin nucleus provides a stringent test of the standard model of particle physics — and anything beyond it.

A precise test of quantum electrodynamics: Measuring the g factor of electrons in hydrogen-like tinQuantum electrodynamics is the best-tested theory in physics. It describes all electrical and magnetic interactions of light and matter. Scientists at the Max-Planck-Institut für Kernphysik in Heidelberg (MPIK) have now used precision measurements on their Alphatrap experiment to investigate the magnetic properties of electrons bound to highly ionized tin atoms. Such tests provide insights into the behavior of particles under extreme field strengths. They also serve as a starting point for the search for new physics.
