Muonium resonance curves in low-pressure argon and krypton at very weak magnetic field were observed at LAMPF by using two line-narrowing techniques, and the result ..delta nu.. = 4 463 302.2 (1.4) kHz (0.3 ppM) was obtained. This is the most precise value of ..delta nu.. yet quoted, and from it were obtained improved values for the muon magnetic moment and mass: ..mu../sub mu//..mu../sub p/ = 3.183 329 9 (25) (0.8 ppM); m/sub mu//m/sub e/ = 206.769 27 (17) (0.8 ppM). 3 figures, 1 table.
