enforceEnergyConservation()

G4bool G4INCL::InteractionAvatar::enforceEnergyConservation ( FinalState *const  fs )

protected

Enforce energy conservation.

Final states generated by the channels might violate energy conservation because of different reasons (energy-dependent potentials, local energy...). This conservation law must therefore be enforced by hand. We do so by rescaling the momenta of the final-state particles in the CM frame. If this turns out to be impossible, this method returns false.

Returns

true if the algorithm succeeded

Store the state of the particles before the interaction.
