Question Changes for heavy ions in GEmStandardPhysics.cc in G4.9.2.p02?

Hello all, I have a problem after switching from G4.9.1.p02 to G4.9.2.p02 in the transport calcultions of heavy ions. I recognized a dramatic change in the ranges of iron ions at high energies. Specifically I calculated the range for Fe56 at an energy of 500MeV/nuc (28GeV) using the G4EmStandardPhysics list. The CSDA range in water in this case is 97.4mm calculated with G4.9.1.p02 which is reasonable but 204.3mm calculated with G4.9.2.p02! What is the reason for this change? Do I have to use a different physics list? In the creation of my physics list I followed the example extended/field/field04. Regards, Daniel
