System for the study of high-resolution electron energy-loss spectroscopy (EELS) on condensed molecules was constructed. Incident electron energy of the spectrometer is variable in the range of 1-30 eV. Condensed layer of CO2 was formed on a clean Ag (111) surface which was cooled to 40 K using a closed cycle refrigerator. Energy loss peaks were observed at 84, 168, and 291 meV, which are assigned to a bending mode, a symmetric stretch mode and an asymmetric stretch mode of CO2, respectively. A few combinational modes were also observed for the exposures larger than 0.5 L. Incident electron energy dependence of vibrational excitation cross-section for the symmetric stretch mode exhibited resonant effect at 9 eV. Incident angle dependence of the cross-section for dipole active modes showed exponential decay as the scattering condition deviated from specular geometry, while the incident angle dependence for the symmetric stretch mode was poor.
