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