None He3 not interacting

I am a Geant4 newbie. I am trying to make a simple He3 interaction in gas (modifying N01 example). I am shooting 1MeV He3 through 25 m of argon and it only transports through the gas and the world. The same is if I replace argon with Pb, so it is more or less obvious that it does not interact. I tried to follow the simple way to add physics:

ExN01PhysicsList::ExN01PhysicsList():G4VModularPhysicsList() {


	RegisterPhysics(new G4HadronElasticPhysics());
	RegisterPhysics(new G4IonElasticPhysics());
	RegisterPhysics(new G4EmStandardPhysics());
	RegisterPhysics(new G4IonPhysics());

    RegisterPhysics( new G4HadronInelasticQBBC(1));	
    RegisterPhysics( new G4DecayPhysics());	    
G4cerr << "constr" << G4endl;

void ExN01PhysicsList::ConstructParticle()
  // In this method, static member functions should be called
  // for all particles which you want to use.
  // This ensures that objects of these particle types will be
  // created in the program. 


void ExN01PhysicsList::ConstructProcess()
  // Define transportation process

G4cerr << "regr" << G4endl;

The constructor and ConstructProcess() are both called, but only transportation seems to take place. Why is the He3 not obeying the physics defined in the contructor?
