Trying with more energies, one can see that hand-made water always results in a stopping power ~ 1.5%-2% higher than G4_WATER for my carbon ion beam.
So then we should assume an uncertainty of the same order for stopping power of all hand-made materials?
In any case, changing the ionization potential of G4_WATER has the same effect as changing it in a hand-made material?
Water = manager->FindOrBuildMaterial("G4_WATER"); Water->GetIonisation()->SetMeanExcitationEnergy(XX.X*eV);
I am also having trouble with response to changes in ionization potential (http://hypernews.slac.stanford.edu/HyperNews/geant4/get/medical_app/215.html) and I am now wondering if it has something to do.
