Abstract: | Diffusion of a thermalized electron in the field of a Coulomb centre is considered. The time dependence of the probability for the electron not to be captured by the Coulomb centre (

D
(t) coincides with the precession amplitude at the muon frequency and is determined by the parameter /l
