摘要：

We present an analysis of the quantum diffusion of muonium in KCl and NaCl crystals, which has been observed experimentally by Kiefl and co-workers. We have demonstrated that all specific low temperature features of D(T) are due to the two-phonon interaction with account taken of the real phonon spectrum. The anomalous behaviour at high T is explained by the effect of "fluctuational preparation of the barrier". Taking both ideas into consideration we found a reasonable theoretical description of the D versus T dependence in a wide temperature range. © 1990.
