Abstract

The dynamics of the muonium (Mu) adduct to C₆₀ in the crystalline state have been investigated using avoided level crossing muon spin resonance (ALC-μSR). The motion of C₆₀ in the orientationally ordered phase (T < 260 K) is well described by a spherical diffusion or isotropic jump-reorientation motion with an Arrhenius activation energy of 176(1) meV and a frequency factor of 2.95(13) × 10^-12 s. This is in striking contrast to the behaviour of MuC₇₀ adducts whose reorientational motion fits well in a pseudo-static model with a temperature dependent order parameter.
