Abstract

In this letter, we present classical trajectory Monte Carlo calculations for single- and multiple-electron ionization of argon atoms and ions in the threshold region. We are able to recover the Wannier exponents, α, for the power-law behaviour of the cross section, δ, versus excess energy: the exact value of the exponent, as well as the existence of its saturation for multiple ionization, appears to be related to how the total binding energy is shared between target electrons.
