I am new to Geant4 and want to simulate the gamma-ray (140 keV and 662 keV) interactions with CZT detectors.
I have created my program. However, the generated spectrum is very strange. There is always a peak next to the 140keV line, and I can see some low energy events but no compton platform. I attached my screenshot to the post.
Is there a full example in the geant4 package that shows how to simulate this simple spectrometer? Or, can anybody help me and share his/her own program?
I appreciate your help in advance.
