摘要：
We present results of a simulation of gamma-ray interactions in a high purity germanium detector (HPGe). Gamma-ray interactions have been divided into Compton events which leave only part of their energy in the detector and full energy events which leave all their energy in the detector. The current pulse shapes from the detector were examined on a pulse by pulse basis. The simulation shows that rejecting all waveforms with trailing edges less than 50 ns improves the peak to Compton ratio by a factor of two and in addition, flattens the remaining Compton edges.
