Question Choosing the Elastic Process  

Keywords: Elastic Process Proton Interaction

Hello,

I need some advice about choosing one of the elastic processes present in Geant4. I am working now with Geant4.9.0.p01 and I see there are the following relatively new processes: G4UHadronElasticProcess and G4QElastic, which I suppose are more updated than the G4HadronElasticProcess one (am I wrong?). My application is intended to simulate protons from 60 MeV to 300 MeV in water and some plastic materials for medical physics. The use of the available hadronic models to describe the nuclear interactions (Intranuclear Cascade + Evaporation) is rather clear for me, but taking into account the importance of the Bragg peak parameters (i.e. peak width) in my application, the selection of the correct elastic process is crucial. Could somebody give me some guideline about the strengths and possible weaknesses of these elastic processes in the way as they were set up in Geant4, and the differences between them?

I would appreciate any help.

Thank you very much,

Katherin
