This situation occursin one of the following 3 cases:1. A photoelectric interaction has occurred and the difference in the electronbinding energy and the secondary particle (X-ray or Auger electron) energy isdeposited.2. Compton interaction has occurred and the electron binding energy is depositedlocally. This is enabled only when the Doppler-broadening option is turnedon.3. The K-shell EII has occurred and the difference between the electron bindingenergy and the secondary particle (K-X ray) energy is deposited. This isenabled only when the EII option is turned on.341
