Perhaps this is somewhat of a novice question, but having read through tons of documents and searching through all of the examples I can't find the answer. Picture we have a neutron moving through a volume that undergoes a (n, gamma) interaction. If I have a UserSteppingAction I can see that it's a neutron by:
if (step->GetTrack()->GetDefinition() == G4Neutron::Definition())
I can also find out the material of the volume:
But this doesn't tell me what the neutron is interacting with. If the material was, say, graphite with a small boron impurity, it doesn't tell me whether the neutron is being captured by carbon as (n, gamma) or interacting with boron as (n, alpha). I mean, I could try working the reaction out from the secondaries, but that'd be pretty awkward. Surely there's a way to find a list of all particles involved in an interaction, even if some of them are just from a volume rather than being actively tracked?
Or is the only way to reverse-engineer it from the secondaries?
