Beschreibung
The measurement of the ground-state hyperfine structure in H-like and Li-like highly charged ions is supposed to provide the best test of QED in the strong magnetic field regime. The measurement of both charge states is required to remove nuclear structure uncertainties, originating in the magnetic dipole moment distribution inside the nucleus (Bohr Weisskopf effect). Such a test has been carried out for
For hydrogen-like
We propose to carry out the experiment on the Li-like ion after the electron cooler has been repaired.
