MULTIPLE IONIZATION IN ARGON AND KRYPTON BY ELECTRON IMPACT
The formation of multiply charged ions by electron impact in argon and krypton was studied with? mass spectrometer. The behavior of the ionization cross section as a function of electron energy was investigated for electron energies up to 600 ev. The ionization potentials in ev were determined to be as follows: Kr/sup 2+/ 38.45 combination rat 0.1, Kr/sup 3+/ 75.6 combination rat 0.5, Kr/sup 4+/ 146.6 combination rat 2, Kr/sup 5+/ 217.5 combination rat 10, Kr/sup 6+/ 350 combination rat 10 Ar/pp 2+/ 43.4 combination rat 0.3, Ar/ sup 3+/ 84.8 combination rat 0.5, Ar/sup 4+/ 150.0 combination rat 5. The shapes of the ionization curves near threshold were studied and discussed in terms of the threshold law for ionization. The maximum cross sections for each multiply charged ion was determined relative to that of the singly charged ion and compared to data obtained by previous investigators. (auth)
