摘要：

The W values and Fano factors for 5.3 MeV alpha-particles have been measured with a gridded ionization chamber and are found to be 43.3+/-0.3 eV and 28.9+/-0.2 eV, and 0.24+/-0.02 and 0.11+/-0.02 for pure helium and helium + argon (1 %), respectively. The W values for both gases agree fairly well with theoretical estimates as well as with previous experimental results and especially with the results of Jesse. The corresponding Fano factors, however, are significantly large compared with those theoretically calculated for the case of electron incidence. The reasons for this difference are discussed.
