Hello everyone !
Does anyone know how to represent HZE ions (high-energy nuclei component of galactic cosmic rays) on a Primary generator in Geant4 ? I’m using a modified version of Hadr06 example in which I put GPS generator . Thank you in advance .

/gps/particle ion
/gps/ion 6 12
/gps/energy 12 GeV

Hello ,thank you for your response, do you know also how can I represent Helium nuclei on that primary generator?
Thank you in advance.

The arguments to /gps/ion are Z and A, respectively. Helium has Z=2, A=4.
