I use GEANT4 to simulate a scintillating crystal (LSO) which is read out by a photodetector. I'm interested in the spread of the arrival time distribution of the first photon in order to study the ultimate time resolution you may get. I understand that the most important figures here are the light yield and the decay constant of the scintillator. But according to 'Yiping Shao 2007 Phys. Med. Biol. 52 1103-1117 A new timing model for calculating the intrinsic timing resolution of a scintillator detector' the scintillation rise time becomes very important for the <1 ns regime. I didn't find a function to set this parameter in the material definition for my crystal. Is this crystal property implemented? If not how may I do it? Perhaps someone wants to post his material definition for LSO. If you don't know the answer to the question perhaps you may may point me to someone who can answer it.
Thank you very much and kind regards,
