Re: Question G4Scintillation - optical photon generation (Bruno Arsenali)

I have corrected N. Thank you for that.

If I use total energy deposit I can see that energy that is deposited during scintillation step for gamma ray with energy of 122keV is 33keV, and number of generated photons is 330. That is as expected because SCINTILLATIONYIELD is 10./keV and RESOLUTIONSCALE 0;

But the thing that I don't understand is that if I look at step 'Delta energy' step->GetPreStepPoint()->GetTotalEnergy()-step->GetPostStepPoint()->GetTotalEnergy() I can see that it is 122keV (for scintillation step). Also I can see that after that step gamma ray stops, because her energy is 122keV and in that step she lost all of her energy.

Base on that I don't understand what happened with the rest of energy (122keV-33keV). I would expect that all energy should be converted to photons. In other words I would like to get 1220 photons from scintillation if gamma ray lose 122 keV.

Can You please be so kind give me explanation or further direction on how to solve my problem?
