I was rereading this thread and I noticed I might have misunderstood your answer. You said you force the charge of an ion to be equal to its mean value depending on its velocity, etc.
Does this mean that YOU fix that value, or does it mean that GEANT is fixing it?
Example: I'm shooting Zirconium ions, at a mean energy of about 100.*MeV. According to the Nikolaev formulae I obtain a mean charge of about +20 for that ion. Now the question is whether I have to shoot ions with a Z of 20 and an A value of 90 (corresponding to Zr) or do I shoot "real" Zr ions (Z=40, A=90) and Geant will deal with the mean charge value to obtain correct results?
