Low energy triple differential cross sections for argon 3s electron impact ionization.
The triple differential cross section for electron impact ionization of the 3s orbital in argon has been measured in the coplanar asymmetric geometry, at a low incident energy of 113.5 eV (less than five times the binding energy) and ejected electron energies of 2, 5, 7.5 and 10 eV. Comparison of two distorted-wave Born approximation calculations with the experimental data reveals very poor agreement.
