| Zusammenfassung | By accurate measurement of total cross section rates for electron-impact ionization and photoionization, total electron-impact cross sections of He were determined. Relative standard uncertainties as low as 1.6 to 2% in the electron energy range from 100 to 4000 eV were achieved using published cross section data for photoionization. Results are discussed in terms of theoretical predictions and by comparison with former experimental results. The data are in excellent agreement with the results by Rejoub et al (2002 Phys. Rev. A 65 042713) and represented an accurate and reliable database for testing theoretical models. |
