I am a geant4 novis.
I have set up an experiment (based on EX02) in which 250 MeV protons are shot at water (50 cm cube).
Everything works fine. I can see the proton track (blue), hits (yellow), secondary e- tacks (red) and gamma tracks (green).
My professor now wants me to investigate how the energy is absorbed at each hit. Is there a way to determine if the proton has collided with an electron or the nucleus? Sometimes (rarely), the proton is deflected at a sharp angle. I assume that this is the result of the proton hitting a nucleus.
Also, is there a way to determine if the hit results in an outer-shell electron excitation or ejection of the water molecule?
I have been looking at TrackerSD::ProcessHits from various examples, but don't see how to do this.
