it is a modified version of the bichsel.mac in the geant 4 extended example TestEM5

If the attached macro file is used in TestEM5 it will create a histogram showing the energy deposited in the detector. It is clearly visible although the energy of the photon incident beam was 30 keV more than 30 keV were deposited in the detector.

modified source code

This is a modified source code of the G4LivermoreComptonModel
it gives a warning every time the bindingE has been set to 0 because it was smaller than 0.
Our studies showed that these warning coincides with the events in which energy greater than the photon incident energy has been deposited in the detector
