Abstract
The electron shakeoff probability of ions resulting from the decay of ions has been measured with high precision using a specially designed recoil ion spectrometer. This is the first measurement of a pure electron shakeoff following nuclear decay, not affected by multielectron processes such as Auger cascades. In this ideal textbook case for the application of the sudden approximation, the experimental ionization probability was found to be in perfect agreement with simple quantum mechanical calculations.
