Hello Marcel,

It seems Geant4 does what you ask -);

You did not include the processes for hadron elastic scattering in your physics list, and as you find, there is no elastic scattering.

Please add a line like:
    // Hadron Elastic scattering
  this-> RegisterPhysics( new G4HadronElasticPhysics("elastic",ver,false));

the ver is the verbosity level, false is a flag indicating that the HP models are not included elsewhere in this physics list. If HP were included ( true ), then the elastic models added here for neutrons should only be used above ~20 MeV, as the HP models take over at low (<~ 20 MeV) energies.
