High Rydberg states of the krypton atom have been investigated at high resolution by vacuum ultraviolet–millimeter wave double-resonance spectroscopy. The measurement of Stark shifts in the spectra of these high Rydberg states is used to determine electric fields with a ±20μV/cm accuracy. The analysis of spectral line shapes provides information on inhomogeneous electric field distributions in the experimental volume.
