G4PreCompoundModel

public G4VPreCompoundModel

Model implementation for pre-equilibrium decay models in geant4. To be used in your physics list, in case you neeed this kind of physics. Can be used as a stand-allone model, but also in conjunction with an intra-nuclear transport, or any of the string-parton models.
