The temperature dependence of the diffusion coefficient is analyzed for the two cases of localized and delocalized positronium in a crystal. The diffusion coefficient for the localized positronium is calculated from the Kubo formula, while that for the free positronium is calculated in the relaxation-time approximation. The temperature dependence of the tunneling diffusion coefficient for positronium is specified by analogy with impuritons in a quantum crystal. [ABSTRACT FROM AUTHOR] |
