the physics of beta-delayed particle emission has been considered and partly already addressed in Geant4. Let me explain.
Particle emission (neutron or proton) from a discrete state (including but not uniquely ground state) to another discrete state is already covered in Geant4. This discrete states can be populated via previous beta-decay processes (thus effectively being beta-delayed). Examples of this have been verified and including more cases is a matter of including them in the dataset.
Now, what it has not been included is the case when either the final or the initial state of the decay are in the nuclear continuum as Geant4 doesn't do nuclear continuum just yet.
There are ideas on how to deal with this and I have look into PRC 88, 041301 (2013) for ideas. It's been on my pipeline for some time already and I hope I get to work on this after summer in time for the next release. Obviously any ideas, complaints or thoughts are welcome.
