摘要：

Electron impact spectra for CO2 have been obtained at 25 different scattering angles ranging from 1.12° to 14.06°. The measured intensities were converted to generalized oscillator strengths and normalized by use fo the Bethe sum rule, leading to the mapping of the Bethe surface over large momentum transfer K and energy loss E ranges. Substantial deviations from the binary encounter theory were observed for K values smaller than 3 au. A discussion is given on the possibility of extracting partial Compton profiles from the data. The total Compton profile was obtained at large K values and found to be in good agreement with recent calculations, within the experimental uncertainties. © 1979.
