[Gate-users] Energy distribution of "ion source" in Gate

[Lee, Sam (SAM LEE)]

Hey,

In Gate, a source can be specified by using "ion source", which takes Atomic number, Atomic weight Ionic Charge, and excitation energy as arguments. I  was wondering how accurately this ion-source models the energy distribution of the isotope. Does it model most of the energy peaks? Can anyone point to me the right documentation in Geant4?

The reason I am asking this question is that I am trying to model all the energies which gets emitted from I-123 source. I was manually specifying energy distribution using histogram keyword to model I123 source energy distribution. I was wondering whether using ion-source to rely on Gate to specify energy distribution automatically is more accurate.

Thanks,
