Dear All
I have obtained following spectrum using DETECT card in FLUKA for 60 keV
gamma falling on 10 micron silicon detector. Here Y-axis is number of
events and X-axis is energy deposit in that event in keV.
[image: Inline image 1]
there was no counts between compton edge (20 keV) and photo peak (60 keV)
but experimental results or results obtained using GEANT4 suggest some
counts between these to points and I found some where that these points are
due to multiple compton events. Following is a similar spectrum obtained
using GEANT4

I have doubt whether FLUKA simulates multiple compton events. Please let me
whether I am missing any necessary card to account multiple compton events.
My input file is attached.
