The Estimation of the G-Values for the Ionization and Excitation of Noble Gases Irradiated by 100 keV Electrons

The binary-encounter collision theory has been applied to the calculation of the G-values for the ionization and excitation of noble gases irradiated by 100 keV electrons. The G-values obtained were as follows in the order of He, Ne, Ar, Kr, and Xe: 2.27, 2.19, 2.81, 3.20, 3.45 for G(electrons), 0.85, 1.55, 1.92, 1.64, 1.51 for G(singlet states), and 0.17, 0.07, 0.13, 0.23, 0.39 for G(triplet states). The method of the calculation and the significance of the results were discussed.
