Abstract
Transverse field muon spin rotation measurements on diamonds with deliberat ely prepared defects show strong temperature dependence of the spin relaxat ion rate of the tetrahedral interstitial muonium species, Mu(T), These resu lts are explained by considering coherent tunneling, below 300 K, followed by deep trapping at the defects. Our results hence provide the first eviden ce of quantum diffusion of neutral Mu(T) in diamond. (C) 2000 Elsevier Scie nce B.V, All rights reserved.
