Hi Daren,

The G4MaterialPropertiesIndex.hh seems to be only available in 10.4, when I check for other version I don't find this document (not sure if it's on my computer end).

(The rat-pac I use is built up on G4.10.01.p03.)

And in this G4MaterialPropertiesIndex.hh, I don't see the parameters like reemission? Also there's xxxSCINTILLATIONYIELD (xxx for proton, alpha, ion, etc), but no single SCINTILLATION that I can input a scintillation spectrum?

I want to understand, how does it work for a common scintillator: (1) I input scintillation spectrum which can be used for producing scintillation photons (and based on the constant scintillation yield); (2) I input a quantum yield and a reemission spectrum, so the photons produced in first step will have some probability (quantum yield) to be absorbed and reemitted to other wavelength of photons (based on the reemission spectrum).

And one step further, what if I have to give a reemission spectrum for every wavelength? In this case, for example, if scintillation photons can have wavelengths A, B, C, then there's reemission spectrum Ra, Rb, Rc.

Thank you.

Aiwu
