We report the first Hall effect measurements on K and Rb doped single crystals of C[sub 60]. The temperature dependence of the Hall coefficient [ital R][sub [ital H]] for each material and the variation in [ital R][sub [ital H]] [ital between] the two materials can be accounted for solely by the variations in lattice constant, yielding a universal relationship of [ital R][sub [ital H]] versus lattice constant for the alkali-doped C[sub 60] systems. The results are interpreted in the context of a strongly disordered system in which the Hall coefficient is sensitive to disorder broadening at the Fermi energy.
