Geant4 Failing to Match with MCNP6 of some peaks on the Inelastic and Capture Gammas spectrum from the simulations of Neutron-Gammas, like Fe/Ti

[idrissi_abdelghani]

I have the same problem with x-rays emitted from a tungsten target.

the simulation shows that the number of x-radiation produced in geant4 is larger in comparison with MCNP code.
