Hello,

unfortunately, it is difficult to find a simple solution for this problem. It happens in FTFP model when target is light like Hydrogen. Because Geant4 has only FTFP model for ion/ion interactions at high energies the same model is used in all Physics Lists. 

If you really need high energy ion interactions, then the only way is to upgrade to the most recent GRAS gras-03-04 and Geant4 10.1p02 where this problem was fixed.
