Dear Michel,

First thank you very much for your effort!

I tried to use your physicsList for my case. The compiler shows that the GammaPhysics.hh and EmStandardPhysics.hh not found, I replace them with in /example/extend/Hadronic/Hadr03/GammaPhysics.hh and G4EmStandardPhysics.hh.

Unfortunately, the result I got using my code is still quite the same.

As you said, it quite difficult to compared your and my results. Perhaps you can attach your code or send to me yuefeng.qiu@kit.edu, so I can extract results using the same way.

BTW, in order to compare with MCNP result, I assume the Li7 density of 1.0g/cm3 (not 1.85 g/cm3), and volume of 1 cm3 (means no need to divide results with volume). I score the track length of neutrons (we call it Neutron Flux, different from Number of Neutrons), and separate total track length into 260 energy bins to get the spectrum. Final result in each bin is divide by Delta Energy (energy normalization). Perhaps these information is useful for you.

Best regards, Yuefeng
