None Inelastic gamma emission from carbon

Hi,

I'm looking at n,n'g on carbon (14.1 MeV neutrons) and the production intensity of the 4.4 MeV line is correct when material is 100 % carbon; however when the material is a mixture the intensity does not scale by the number density of carbon in the mixture i.e.

G4Material* PlasticMat = new G4Material("PlasticMat",1.00*g/cm3, 2); PlasticMat->AddElement(Hydrogen, 1); PlasticMat->AddElement(Carbon, 1);

This material should produce 50 % gamma emission compared to:

G4Material* carbon = new G4Material("carbon",1.00*g/cm3, 1); PlasticMat->AddElement(Carbon, 1);

I'm using the QGSP_BERT_HP physics package for this...

Also, the n,n'g reaction produces lines above 4.4 (7, 9 and 11.5 MeV) all of which are incorrect; these levels should decay via alpha/other emission, not gamma emission. I can easily remove these by setting the volume sensitive and killing them, but I'd prefer not to have to!).

Any help would be great.

Thanks,

Mike.
