Longitudinal Muon Spin Relaxation In High-Purity Aluminum And Silver

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 lambda(Al) = 1.3 +/- 0.2 (stat.) +/- 0.3 (syst.) ms(-1) and lambda(Ag) = 1.0 +/- 0.2 ( stat.) +/- 0.2 ( syst.) ms(-1).
