MUON SPIN-ECHO

A muon spin echo method is proposed for determining the contributions of the static and dynamic local fields in muon experiments. It is show n that if for each muon which has stopped in the sample a rf pulse of fixed duration is applied to the sample at a time tau after the muon e ntered the sample, then after a sufficient number of muon-positron dec ays have been accumulated a muon spin echo can appear at time 2 tau.
