摘要：

Energy loss features for solid C60, matrix-isolated C60 in Xe, and for small amounts of C60 on Xe showed differences related to the rare gas environment. In contrast, losses related to on-site pi-pi* shake-up features were unchanged. The energy of the molecular it plasmon shifts approximately 0.8 eV to lower binding energy for matrix isolated C60 due to the dielectric response of the surrounding medium. The work function of solid C60 is 5.0 eV. Its ionization potential of 7.2 eV shows a reduction by 0.4 eV relative to the gas phase because of dielectric screening.
