Abstract
Detection of a level crossing resonance establishes that a molecular radical is created in elemental sulphur following the implantation of positive muons. Formally this is the product of the reaction of atomic muonium with the S8 rings and must serve as a model for the fate of interstitial atomic hydrogen in this element. The isotropic component of the muon-electron hyperfine interaction is determined to be 233 ± 5 MHz. Preliminary data for the temperature dependence of the resonance linewidth indicates a substantial motional narrowing of the anisotropic components.
