Abstract We report longitudinal fieldμSR 1/T 1 measurements in Si from room temperature to 850 K. The data in pure Si and Si∶B (p-type) can be explained in a two-state model where muonium cycles between its positive and neutral charge states. Within this model, the average muon-electron hyperfine parameter in the neutral state is consistent with muonium at the tetrahedral interstitial site, indicating that at the highest temperatures measured, neutral muonium spends a significant amount of time away from the bond centered site, the calculated potential minimum. Although this is also true for Si∶P (n-type) at high temperatures, the data in the region between 300–450 K indicates that at least one other state is involved in the dynamics.
