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 time-differential \musr. For times greater than 10 ns, the shape fits well to a single exponential with relaxation rates of $\lambda_{$\text{Al}$} = 1.3 \pm 0.2,($\text{stat.}$) \pm 0.3,($\text{syst.}$),\pms$and$\lambda_{$\text{Ag}$} = 1.0 \pm 0.2,($\text{stat.}$) \pm 0.2,($\text{syst.}$),\pms$.
