摘要：

LF mu SR studies on the pure fullerenes C-60 and C-70 show temperature dependent features associated with the reorientational behaviour of the fullerenyl radicals MuC(60) and MuC(70) in the crystalline host substrate. If not excluded from the experimental setup, molecular oxygen undergoes spin exchange reactions with the radicals. The data for C-60 correspond to a situation effectively static at 150 K and fully averaged to isotropy at 300 K, while for C-70 the data conspicuously do not conform to the predictions of the pseudostatic model employed in ALC-mu SR studies.
