• Gryzinski's classical treatment of the double ionization has been used to estimate the contribution of the double-collision process to the <I>G</I>-values of the ionizations and excitations of noble gases irradiated by 100 keV electrons. Except for helium, the double collision accounted for 5–15% of the yield of electrons. The total <I>G</I>-values calculated are ultimately as follows (in the order of He, Ne, Ar, Kr, and Xe): 2.28, 2.53, 3.09, 3.41, 3.67 for <I>G</I>(electrons); 0.84, 1.37, 1.78, 1.54, 1.41 for <I>G</I>(excited singlet states); 0.17, 0.07, 0.13, 0.23, 0.39 for <I>G</I>(triplet states).
