Threshold Double Photoionization of Argon with Synchrotron Radiation

Abstract : Auger satellite have been measured to determine the probability of M- shell excitation accompanying K-shell photoionization of Ar, as function of photon energy. The theoretically predicted difference between the dependence of shakeup and shakeoff probabilities on the photon energy near threshold is demonstrated. Results are critically compared with calculations. Originator- supplied keywords include: Photoionization, Synchrotron radiation, Electron correlation, and Atomic physics.
