Abstract

High precision measurements of two Zeeman hyperfine transitions in the ground state of muonium in a strong magnetic field have been made at LAMPF using microwave magnetic resonance spectroscopy and a resonance line narrowing technique. These determine the most precise values of the ground state hyperfine structure interval of muonium Δν = 4463302765(53)Hz (12ppb), and of the ratio of magnetic moments μ_μ/μ_p = 3.18334513(39) (120ppb), representing a factor of 3 improvement. Values of the mass ratio m_μ/m_e and the fine structure constant a are derived from these results.
