Abstract
The splitting of the tetrahedral Rb- and K-NMR lines in Rb3-xC60 and K 3-xC60 is analyzed in terms of the mechanism of alkali-cation vacancie s. The calculations indicate the presence of vacancies only in the tet rahedral positions, and the interatomic potentials between the alkali cations and the fullerene molecules account satisfactorily for the tem perature dependence of the position of the distorted line.
