Aha, I see. That makes sense. Thanks!
@whokion Looking at how G4HepEm does this for grammas: https://github.com/mnovak42/g4hepem/blob/0b1c7ecea142e5fa0867d39faaaf7f360f7fce24/G4HepEm/G4HepEmInit/src/G4HepEmGammaTableBuilder.cc#L123-L124 It seems G4HepEm is only approximating the cross sections by tabulating them, not actually calculating them on the fly. It...
Ah nice! That's a great reference.
- Hit reconstruction will contain ActionId which can encode a process if needed (gamma vs electron) - Call ApplyYourself which will create secondaries (with associated G4HadProjectile and G4Nucleus target), modify...
Some follow-on thoughts. # Guiding principles I think we want first and foremost, **Enabling Celeritas maintains consistent physics with Geant4**. Less important but still worth considering, as you mentioned is,...
Note from our discussion Friday that LArSoft currently uses Geant4 10.6 but is encouraging its users to move to 11.4 .
Awesome! I was hoping to fix this myself if it wasn't already taken care of upstream. Yep it is an error with HTML named character entity references being translated literally...
No, I think we either want something with the particular features ATLAS requires (separation by particle type, etc) or rely on a stepping action feedback mechanism.

Initial completion in #1720.
