Detailed Description

INCL++ intra-nuclear cascade.

Interface for INCL++. This interface handles basic hadron bullet particles (protons, neutrons, pions), as well as light ions.

Example usage in case of protons:

G4INCLXXInterface* inclModel = new G4INCLXXInterface;
inclModel -> SetMinEnergy(0.0 * MeV); // Set the energy limits
inclModel -> SetMaxEnergy(3.0 * GeV);
 
G4HadronInelasticProcess* protonInelasticProcess = new G4HadronInelasticProcess( "protonInelastic", G4Proton::Definition() );
G4VCrossSectionDataSet* protonInelasticCrossSection = new G4BGGNucleonInelasticXS( G4Proton::Proton() );
 
protonInelasticProcess -> RegisterMe(inclModel);
protonInelasticProcess -> AddDataSet(protonInelasticCrossSection);
 
particle = G4Proton::Proton();
processManager = particle -> GetProcessManager();
processManager -> AddDiscreteProcess(protonInelasticProcess);

The same setup procedure is needed for neutron, pion and generic-ion inelastic processes as well.
