摘　　要：For near monolayer(ML)C_(60) condensed on Sn substrate,x-ray photoemission studies of Cls level reveal a feature centered about 22eV below the main peak.Analyses show that the feature is caused by the plasmon loss of the two dimensional C_(60) film.Bulk plasmon loss peak(~28 eV blow the main peak),which has been observed on thick C_(60) films,was not observed on the C_(60) films with coverageθ<2 ML.It indicates that the 28eV energy loss feature is due to a bulk plasmon associated with the solid C_(60) but not a single C_(60) molecule.
