在LAMPF装置上，我们用两种谱线窄化技术在极弱磁场下观测到低压氩和氪中的μ ~+共振曲线，得到Δv = 4463302.2（1.4）kHz（0.3ppm）。这是迄今引用的最精确的Δν值，由此我们得到μ子磁矩和质量的改进值：μμp= 3.183 329 9（25）（0.8 ppm）; mμme= 206.769 27（17）（0.8 ppm）。
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: μμp= 3.183 329 9 (25) (0.8 ppm ); mμme= 206.769 27 (17) (0.8 ppm ) .
