Muon Diffusion and Trapping in Solids
This paper surveys the theory underlying studies of muon motion in solids. It covers what is measured in muon experiments as well as the various forms of muon motion. The basic theory for metals is the quantum theory of diffusion, supplemented by the phenomena associated with trapping. In insulators and semiconductors there are extra effects associated with the several possible charge states and with ionisation-enhanced motion.
