Re: Question Questions about QBBC Physics List (Zach Miller)

I think I have answered my own question for question 1.

In order to match up with ENDF, I am having to multiply my (GEANT's) answer by the (atomic mass)/100. So for 1-H, I multiply by 0.01. For 16-O, 0.16. For 12-C, 0.12. I'm not sure why this factor is occurring in my GEANT results. I'm defining my materials like this:

 G4Element* H = new G4Element("Hydrogen", "H", z=1 , a=1.01*g/mole);
 G4Material *Hyd = new G4Material("Hyd", density=0.08*g/cm3, nelements=1);
 Hyd->AddElement(H,1);

Any guidance on why this is behaving so strangely? I could still use guidance on my second question in my previous post as well, I've found that the 12C inelastic cross-sections are also suffering from a similar problem to what I describe (averaging over wide energy ranges to get general behavior).

Many thanks, Zach
