Hi Peter,

I tried to avoid the overlap but I couldn't. I still don't understand how to do that. I want photons to be scintillated by e- in a volume with one energy and then be absorbed and reemitted in the wls fiber with another and only one energy. I gave an answer to it by giving different arrays to scintillation and emission, but it gives Warnings and a lot of them. Giving one array to both of them doesn't give the result I wish. It gives all possible energies. And the worse is that those photons (in the wls fiber) are being absorbed and reemitted without losing any energy, which is not physical. I now have what I need, but the program is computer dependent, it gives me Segmentation fault on other computers. If it is possible please give me an example of the not overlapping spectrum program. Thanks for the assistance.
