| Abstract: | Muonium spin relaxation measurements of the \alpha‐, \beta‐, and \gamma‐tridymite phases of quartz have been carried out over
a temperature range from 300 to 1250 K. Anomalous relaxation rate increases are observed which may result either from resonance
coupling between the other impurity ions and defects in the lattice and the diffusing muonium, or may result from phonon interactions
with the muonium quadrupole moment.
