This is a kind of model decision. We prefer to establish conservation by emitting artifical gamma or adjusting secondary particles (not only for gamma) and at the stage, we do not know a gamma is an emission of characteristic or continues. You may set an environment variable of “G4NEUTRONHP_DO_NOT_ADJUST_FINAL_STATE”, under this, some efforts for the establishment are skipped and you may have better characteristic gammas.
