Extending g-factor measurements to heavy, highly-charged ions
Joseba Alonso (Institut für Physik)

Bound-state quantum-electrodynamical calculations can be tested by high-precision

measurements of the magnetic moment of the electron bound in hydrogenlike and lithiumlike ions. Measurements of hydrogenlike carbon and oxygen achieved relative experimental uncertainties as low as 2·10⁹. In the current experiment we plan to measure the g-factor of hydrogenlike and lithiumlike calcium ions. The aim is to reach a relative uncertainty Δg/g in the order of 10⁹. The motivation for the experiment will be given and the experimental techniques and current status presented.</p>
