New physics model in GEANT4 for the simulation of neutron interactions with organic scintillation detectors

There is an article with the same name:
Is this article was implemented in recent Geant4 versions? If yes, from which version and what is the name of the model? If not, will it be implemented? If yes, when?

So far I don’t see correct treatment of C12(n,3a) reaction in any of the generic physicslists.
