【 摘 要 】

The ion-impact induced ionization of small molecules was investigated both experimentally and theoretically. Electron energy spectra were taken by an energy dispersive electrostatic spectrometer at different observation angles. The obtained absolute electron emission cross sections were compared with the results of CDW-EIS and CTMC calculations. Both theories are in a reasonable agreement with the experimental data.
