Angle-dependent interference was observed in (e,2e) coincidence observations of argon L2,3M2,3M2,3 Anger transitions. The (e,2e) dynamics include an incident energy of 1.0 keV, a fast electron scattering angle of 21 degrees for an energy range from 730 to 760 eV with 2.5 eV resolution and Auger electron detection angles of 60 degrees and 90 degrees. Observations were made below the Auger threshold and with excess energies of 22, 2, and 0.5 eV. The interference, attributed to the interaction of Anger and satellite-state ionization processes, and the post-collision-interaction effects are quantified.
