Question Physics List for Fission fragments as source particles in a gas 

Forum: Physics List
Date: 29 Jul, 2015
From: Francesca <Francesca>

Dear all,

   I am not a C++ expert and I am trying to customize a Physics list 
optimized for a simulation where the primary particles are 
fission fragments. The goal is scoring the energy deposited by the FFs in 
a gas, and finding out the number of FFs that do not leave a Pu target. 
By making some copy & paste (withouth really understanding what I am doing...) I get the electromagnetic physics initialized by activating "Livermore", but when it comes to the hadronic pyisics list, I have no idea of how to proceed...
I can Initiate HadronInelasticQBBC, but ... 

1. does QBBC suit to this kind of simulation?

2. Judging from its name, HadronInelasticQBBC is only for Inelastic processes. Actually that's what I need, but -accademically speaking- in case I want to add also ElasticProcesses, how should I proceed?

Could anyone help me, please?

Thanks, regards,


---------------- My PhysicsList.hh looks like:


#include "G4VModularPhysicsList.hh"
#include "globals.hh"
#include "G4EmConfigurator.hh"

class G4VPhysicsConstructor;

class PhysicsList: public G4VModularPhysicsList { public:


  virtual ~PhysicsList();

  void ConstructParticle();

  void ConstructProcess();

  void SetCuts();

  G4EmConfigurator em_config;

  G4VPhysicsConstructor*               emPhysicsList;
  G4VPhysicsConstructor*               decPhysicsList;
//  G4VPhysicsConstructor*               hadPhysicsList;
  std::vector<G4VPhysicsConstructor*>  hadronPhys;

}; #endif
