As we know, characteristic x-rays can be generated if below are used.
G4VAtomDeexcitation* de = new G4UAtomicDeexcitation();
G4LossTableManager::Instance()->SetAtomDeexcitation(de);
de->SetFluo(true);
I was just wondering which “physics process” is used in Geant4 to describe the generation of characteristic x rays?
For example, “eIoni” is the process name for electron ionization. so, my question is what is the process name for generating characteristic x rays?
Atomic deexcitation (x-rays, fluorescence, Auger e-) is not a process by itself, but an optional component of the final state of several processes : photoelectric, Compton, ionization.
So, there is not a specific “process name” for this phenomena.
Thanks so much for your answer, Michel.
now I understand the three options for the atomic de excitation.
In the G4VAtomDeexcitation Class,
there are: SetFluo(), SetAuger() and SetPIXE() functions.
I have one more question.
Since PIXE is used for describing characteristic x rays, as explained here: https://www.ge.infn.it/geant4/physics/pixe/
so, the statement in my original question is incorrect. I said fluo is for characteristic x rays.
Now, my question is: what phenomenon is fluo used to describe?
Thanks again.
