Title: Argon-photoion--Auger-electron coincidence measurements following K -shell excitation by synchrotron radiation

Abstract

Argon photoion spectra have been obtained for the first time in coincidence with {ital K}-{ital LL} and {ital K}-{ital LM} Auger electrons, as a function of photon energy. The simplified charge distributions which result exhibit a much more pronounced photon-energy dependence than do the more complicated noncoincident spectra. In the near-{ital K}-threshold region, Rydberg shakeoff of {ital np} levels, populated by resonant excitation of {ital K} electrons, occurs with significant probability, as do double-Auger processes and recapture of the {ital K} photoelectron through postcollision interaction.
