The time dependence of muon spin relaxation has been measured in high-purity aluminum and silver samples in a longitudinal 2 T magnetic field at room temperature, using the time-differential muon spin relaxation technique. For times greater than 10 ns, the shape fits well to a single exponential with relaxation rates of λAl=1.3±0.2(stat.)±0.3(syst.)ms-1 and λAg=1.0±0.2(stat.)±0.2(syst.)ms-1.
