Description

We report the first measurement of the polarization of thermal muonium in vacuum. A 20 MeV/c beam of μ+ was stopped in a layer of SiO2 powder which emitted (17 ± 1)% of the stopped μ+ into vacuum as thermal muonium. The muonium Larmor precession was observed in a transverse magnetic field of 1.4 G, and the measured amplitude of the precession signal indicates that the μ+ polarization in the muonium is (39 ± 9)%.
