Hi Mary,

  These energies are too low for most Geant4 hadronic models, which were
typically designed for hundreds of MeV up to a TeV.   As a result, there
has been little validation in this region (except for neutrons) and it is
not surprising that you got such different results.  Note that the 
G4LEProtonInelastic model does not produce gammas, so you should not use 
it in this particular application.  None of the other three models 
(Bertini, Binary, Precompound) have been validated at 10 MeV.  The 
precompound model has been validated a little at 30 MeV, but not for 
outgoing gammas.  There is really only one way to know which model is 
best:  compare to data if you have it.   If not, you need to make some 
guesses as to what is reasonable.   An educated guess on my part would
prefer the Bertini model (G4CascadeInterface).

Dennis
