R. Elmkhanter et al., ON THE MECHANISMS FOR DOUBLE-IONIZATION - A STUDY OF (E,3-1E) EXPERIMENTS ON ARGON, Journal of physics. B, Atomic molecular and optical physics, 29(5), 1996, pp. 1101-1107
The recent double-ionization experiments (e, 3 - 1e) on argon by elect
ron impact are, for the first time, investigated theoretically. Simple
qualitative models and more elaborate theoretical calculations are pr
oposed and discussed in order to understand the mechanism of double io
nization at high electron impact.
