Abstract
The occurrence and significance of interference effects1 observed in electron-impact (e,2e) coincidence measurements of Auger transitions2,3, has aroused considerable interest. We report the first detailed observations of the strong angular behaviour of the interference phenomena, and the quantified behaviour of the interference and post-collision-interaction (PCI) effects on the argon L2,3M2,3M2,3 Auger lines. Excess energies up to 18 eV above the L2,3 inner-shell ionization threshold were used. The interference is attributed to interaction between the outer-shell satellite-state ionization processes, identified in coincidence4, and the Auger processes.
