Abstract
Using X-ray photoemission measurements, we have determined the attenuation length of C 1s photoelectrons in C 60 film to be 21.5 Å with the incident photon energy of Mg Kα 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. K 3C 60, K 6C 60, Ba 4C 60, Sm 2.75C 60 and Sm 6C 60 are calculated to help the quantitative analyses of the photoemission spectra for these compounds.
