Abstract

Using an improved one-step theory of electron shakeoff, we have performed rigorous calculations of the energy-dependent K-shell internal ionizaton probability. The measured probability for Pm147 considerably exceeds the theoretical curve at low electron energies. This suggests that the direct collision process may play an important role when both a β particle and a K electron are emitted with low kinetic energies.
