Measurements of Zeeman transitions in the ground state of muonium at strong magnetic field have yielded values for the hfs interval, Δν=4463 302.35(52) kHz (0.12 ppm) and for the muon magnetic moment, μμμp=3.183 3403(44) (1.4 ppm), of considerably higher precision than previous results. The theoretical expression for Δν, including our measured value of μμμp, disagrees with the experimental value by 2.5 standard deviations. The electronic gJ density shift for muonium in Kr has been measured.
