This paper reported our precision microwave spectroscopy of the muonium ground-state hyperfine structure at J-PARC. Using the intense pulsed muon beam and a highly segmented positron detector, we observed the resonance near zero magnetic field and obtained a hyperfine interval consistent with previous precision measurements and theory.
