Abstract The temperature dependence of ESR linewidths and {ital g} values for the fulleride superconductors K{sub 3}C{sub 60}, Rb{sub 3}C{sub 60}, and Na{sub 2}CsC{sub 60} are reported. Following the Elliott-Yafet theory of electronic relaxation in metals, we compare the temperature dependence of the linewidth divided by the square of the difference of {ital g} from the free-electron value with the temperature dependence of the resistivity. We show that the Elliott relation applies for all three compounds, implying a normal-state resistivity dominated by electron-phonon interactions. {copyright} {ital 1996 The American Physical Society.}
