Abstract

We present measurements of the transverse (T 2 −1 ) and longitudinal (T 1 −1 ) spin relaxation rates of muonium (Mu) atoms in solid natural xenon (n-Xe) as well as pure136Xe (which has no nuclear moments). The temperature dependences ofT 2 −1 andT 1 −1 in natural Xe belowT ∼ 115 K demonstrate the quantum character of Mu diffusion governed by one-phonon interactions. Taking into account both the polaron effect (PE) and the effect of fluctuational preparation of the barrier (FPB) makes it possible to consistently describe Mu diffusion in Xe. Mu spin relaxation in136Xe at high temperatures is not due to nuclear hyperfine (NHF) interactions.
