Abstract

Direct evidence is presented for thermally activated muonium formation in Al2O3 and BaF2. In each case the signature of the transition is a transverse field depolarization rate of the prompt diamagnetic component which is much too large to be attributable to muon-nuclear dipolar couplings. Longitudinal field decoupling measurements in Al2O3 support the interpretation that the initial diamagnetic fraction converts into a state with a stongly coupled electron —-i.e., muonium.
