ELECTRON-ENERGY-LOSS SPECTROSCOPY OF THE C-60 MOLECULE

In this work we present a theoretical study of EELS (electron-energy-l oss spectroscopy) experiments on the C-60 molecule. Our treatment of t he problem is based on the simple two-fluid model originally proposed for the description of plasma oscillations in graphite and fullerenes [J. Cazaux, Solid State Commun, 8 (1970) 545; Opt. Commun. 2 (1970) 17 3; G. Barton and C. Eberlein, J. Chem. Phys. 95 (1991) 1512]. It is sh own that in spite of the simplicity of the model the calculated intens ities of the EELS peaks are in good agreement with experimental data w hich may indicate that the model can be used as a simple and effective tool for the investigation of the collective behaviour of electrons i n fullerene ne systems.
