Abstract

The temperature-dependent resistivity of Rb-doped single-crystal C60 is analyzed within Bloch-Boltzmann transport theory yielding values of the electron-phonon coupling constant consistent with a superconducting Tc30 K and isotope effect exponent 0.37 as long as the coupling is not primarily to the on-ball phonons of highest frequency. Disparate sources of information regarding the absolute magnitude of the resistivity are discussed in an attempt to form a more unified picture of the normal state and superconducting properties of both K-doped and Rb-doped C60.
