Hello Eva,

Can you please check if there are any warnings or error messages just 
before the line "** Geant4 Hadronic Reaction Information ***"?

Which release of geant4 are you using?
Also, please give details on the physics list you are using; we would 
need to know which model would be responsible to handle inelastic 
reactions for neutrons with 190 Mev momentum, or about 19 MeV kinetic 
Energy?
