Hi I wish to ask a quastion about the spectrum of Prompt gammas obtained from Geant4 simulations.
I the process which I considered 63 MeV protons are interacting with carbon and energy spectrum of emitted gammas in registed.
The issue is that for 4.4 MeV peak of gammas the sharp peak at exactly 4.43 MeV bean is created and it is quiet separated from the background and braked the continuity of spectrum in some sense.
I which to ask if this problem might be caused by the physics model used (QGSP_BIC) ?
I attached also the histograms showing the peak shapes.
