Abstract
Precise determination of bound-electron g-factors in heavy highly-charged ions (e.g. Bi82 + , U91 + ) provides a stringent test of bound-state QED in extreme fields. With a laser-microwave double-resonance technique we will probe the microwave transitions between the Zeeman sub-levels of the hyperfine structure in highly charged ions. From this the bound electron g-factor gJ can be determined. We present the experimental progress of this novel method to measure the g-factor of the bound electron in highly charged ions.
