摘要：
In this work we present a theoretical study of EELS (electron-energy-loss spectroscopy) experiments on the C60 molecule. Our treatment of the 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) 173; G. Barton and C. Eberlein, J. Chem. Phys. 95 (1991) 1512]. It is shown that in spite of the simplicity of the model the calculated intensities of the EELS peaks are in good agreement with experimental data which may indicate that the model can be used as a simple and effective tool for the investigation of the collective behaviour of electrons in fullerene systems.
