Hello Steve,

I am no expert on this particular part of Geant4, but I would suggest looking at the G4Incl class. It has the switches to turn Fermi Breakup on and off, and the registerLogger method looks like it might be used to record information - like, say, about when fermi breakup is used.

Failing this, you could use the Geant4 cross-reference (which you can get to via the user support page from the geant4 homepage) to look for places where G4FermiBreakup is referenced. You could then create your own extension of these classes, or of G4VFermiBreakup itself, either to add logging or to increase the frequency of breakup (though in the latter case, you would have to be very, very careful about how you interpret your results).

Hope this helps, Joel Long
