I am trying to implement scintillation for my NaI detector code. I went through your ExN06 in order to understand how this is done in GEANT4. I am very confused about several things in ExN06:
1). I see a table of 32 optical photon energies, but, I do not see a table showing the corresponding "relative strength" for those photons, in order to define their actual distribution or emission spectrum. E.g. NaI emission peaks at 415 nm, BUT, there is a distribution around that value (with relatively weaker emission at neighboring wavelenths). HOW DO YOU ACTUALLY DESCIBE THE DISTRIBUTION OF THE EMITTED OPTICAL PHOTONS IN GEANT4????
2). There is mainly 1 time constant for NaI: 250ns. I guess I can set both the FASTTIMECONSTANT, and the SLOWTIMECONSTANT to 250 ns there. What puzzles me is the 2 tables in ExN06 each with 32 entries named "ScintilFast[nEntries] and ScintilSlow[nEntries]: What are those numbers???? Thanks for helping, Clarisse
