摘要：

We present C 1s autoionization studies of condensed and Xe matrix-isolated C60 molecules which give direct information on electron hopping rates in solid C60 in the presence of a C 1s vacancy. These rates vary dramatically for the first three C 1s absorption excitation maxima in a pattern consistent with strong electron-electron correlations. Hopping associated with the second excited state involves extramolecular screening comparable to the Mott-Hubbard pseudogap predicted for K3C60, suggesting intramolecular correlations do not dominate electron transport in the alkali fullerides.
