摘要：

Using X-ray photoemission measurements, we have determined the attenuation length of C Is photoelectrons in C-60 film to be 21.5 angstrom with the incident photon energy of Mg K alpha radiation. The inelastic mean free path calculated with the TPP-2M algorithm coincides fairly well with the experimentally determined attenuation length, indicating the validity of the algorithm to fullerene and fullerides. The inelastic mean free paths for some fullerides, i.e. K3C60, K6C60, Ba4C60, Sm2.75C60 and Sm6C60 are calculated to help the quantitative analyses of the photoemission spectra for these compounds.
