The spin lattice relaxation of 8Li in simple metals

We report the modification to the linear temperature dependence of the Korringa nuclear spin-lattice relaxation rate of an implanted NMR probe in silver, as it makes a thermally activated site change. We develop a simple model of this phenomenon, which is found in a number of metals including Au and Nb. (C) 2008 Elsevier B.V. All rights reserved.
