Why Are There Counts Between Compton Edge and Photopeak in Gamma Spectroscopy?

Click For Summary
SUMMARY

The discussion addresses the discrepancy between theoretical expectations and practical observations in gamma spectroscopy, specifically regarding the counts between the Compton edge and the photopeak. It is established that energy resolution of the detector plays a crucial role in this phenomenon. Theoretical models suggest that counts should be zero in this region, but real-world data often shows otherwise due to detector inefficiencies. Understanding these factors is essential for accurate gamma spectroscopy analysis.

I know that theorically the numbers of counts between compton edge and the photopeak must be zero. In practice it doens't occur. Why?
Thanks in advance!
