Range in different Geant4 versions

Dear experts,

I would like to ask related to the range contradiction of Bragg curves in different Geant4 versions.
I am simulated incident 313.2 MeV/u carbon ions in PMMA phantom using Geant4 versions 10.3.3, 10.6.3, and 11.1.0
I got similar results for versions 10.3.3 and 10.6.3 but version 11.1.0 have a different range as attached image.

I am confused about which Geant4 version that provides the correct result.
I’d appreciate any help on this.



10.6/10.7 should be better. I suggest you compare your results against published results for double checking. The shift in 11.1 is currently under investigation.

Dear Dr. Susanna,

Thank you so much for your kind answer.
FYI, when I changes of mean excitation energy (I) of PMMA material in Geant4 version 11.1.0 will shift the range of Bragg curves but in version 10.6 different I-value is not shift the range of Bragg curves of Carbon ions.
