Muonium in bulk fused quartz: Test case for RAHD relaxation theory.

Muonium (mu sup + epsilon sup -) in bulk fused quartz is a unique system in that the mu sup + spin polarization (in the muonium state) relaxes almost entirely via random anisotropic hyperfine distortions (RAHD). As such, this system provides an excellent test case for a new RAHD spin relaxation theory. This theory is quantitatively compared to static zero field data and the functional characteristics in both the high field and dynamic limits are considered as well.
