Low-temperature diffusion of positive muons in copper

Measurement of the depolarization of positive muons in copper in zero external field shows that the hopping rate of the muons increases as the temperature decreases from 4.2 K to ∼ 1 K. This is the first unambiguous demonstration of muon diffusion behavior which is not thermally activated.
