We propose a hopping model for the diffusion, and use it to analyse time-domain [mu]SR data. It is found that the diffusion is an incoherent quantum process, with an activation energy of 5.2(2) meV. The analysis also points to the anti-bonding site as the best-suited candidate for the muon's localisation. | URI: | https://hdl.handle.net/10316/4409 | DOI: | 10.1016/j.physb.2005.11.122 | Rights: | openAccess |
