Inhaltszusammenfassung
A high-resolution experimental photoemission spectrum of C60 is compared with calculations including the Jahn-Teller effect and multiple phonon satellites. The spectra show discrete loss features due to the excitation of phonons. From the intensity of these features electron-phonon coupling constants are derived which support the electron-phonon mechanism for superconductivity. The systematic deviations from previously calculated coupling constants are discussed in detail.
