I have a few questions about optical processes in Geant4:
1) In the scintillation process, how does Geant4 decide the energy of each photon produced? Does it use information about the scintillation material (molecules) at all? I ask this because the examples N06 and LXe do not seem to define a range for the photon energies, just the photon number yield. (and what about photon polarization?)
2) If I want to simulate total internal reflection between two dielectrics, is it imperial that I declare the border surface polished? Does a ground border surface accounts for total internal reflection?
3) I have a world volume filled with vacuum and two other volumes standing side by side, with surfaces intersecting at z=z0. A logical border surface is declared between physical volumes for all possible 3x2=6 possibilites. When a photon is incident from one of the volumes into the next, does Geant4 runs 2 optical boundary processes between each of the volumes and vacuum (i.e. is there an "intrinsic" gap between the volumes?)
