Sad Sensitive detector doesnt work 

Forum: Biasing and Scoring
Date: 24 Feb, 2015

Dear Geant4 enthusiasts!
I am a beginner and I am stuck for a while with this problem. Please help me out.

I have a pixelated Silicon absorber (12um thick). I am shooting 5.9 keV gammas using GPS to it. I want to see the detected energy spectrum in a histogram.

I defined the Silicon absorber as sensitive detector. But, still I see all the particles in the histogram, all having 5.9 keV energy. Means 100% absorption of 5.9 keV gamma in a 12 um thick Silicon, its not possible.

What I am doing wrong or what is missing? Any help or suggestion will be appreciated.
