title = "A new high precision measurement of the muonium hyperfine structure interval Δv1",
abstract = "At LAMPF we have observed muonium resonance curves in low pressure argon and krypton at very weak magnetic field using two line narrowing techniques, and have obtained Δv = 4 463 302.2 (1.4) kHz (0.3 ppm). This is the most precise value of Δν yet quoted, and from it we obtain improved values for the muon magnetic moment and mass: μμ p = 3.183 329 9 (25) (0.8 ppm); mμ me = 206.769 27 (17) (0.8 ppm).",
