Quantum tunnelling of muonium in copper(I) chloride MacFarlane, W. Andrew


The unusual behaviour of paramagnetic muonium centres in the binary semiconductor Copper(I) Chloride at low temperatures lacks a satisfactory explanation. In this thesis, after a brief review of the experimental results to date, a model for the spin dynamics of the muon as it undergoes local quantum tunnelling motion amongst four wells arranged in a tetrahedron is presented. Calculations based on this model suggest that a level crossing resonance associated with the tunnel splitting could be observed in a 1iSR experiment.
