Abstract

The strong collision model is used to calculate spin relaxation of a muon or polarized radioactive nucleus in contact with a fluctuating environment. We show that on a time scale much longer than the mean time between collisions (fluctuations) the longitudinal polarization decays exponentially with a relaxation rate equal to a sum of Lorentzians-one for each frequency component in the static polarization function p_s(t).
