A new high precision measurement of the muonium hyperfine structure interval ∆v1
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 ∆v = 4 463 302.2 (1.4) kHz (0.3 ppm). This is the most precise value of ∆ν 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).
