We have measured the distribution of photoion charge states resulting from vacancy cascades and electron shakeoff following {ital K}-shell photoionization of Ar{sup 2+} ions. The Ar{sup 2+} ions were produced by electron-impact ionization of Ar, stored in a Penning ion trap, and then photoionized using broadband synchrotron radiation. Time-reversed integration of coupled differential equations was used to account for contributions from electron capture with residual gas. The results are in reasonable agreement with a simple theoretical prediction.
