High Energy Particles

Dear Users,

I am running Geant4 simulation for high energy particles i.e fission fragments. I have a question on describing the energy and atomic mass of the particle in the input file. Could anyone here advice me on the best way to write the input file. In Geant4 manual, the description is to write the high energy particle is : /gun/ion z a Q

Here is an example I used for Zr with mass number of 100 and energy of 94.190 MeV

/gun/particle ion
/gun/ion 40 100
/gun/energy 94.190 MeV
