  Indeed  this is what the example does, because :
  1- there is no Em processes registered
  2- event is killed at first step. So, this unique step is always governed by hadronic interaction, according the exponential law.

 Also, you will see how to extract hadronic cross sections from Geant4 data tables via G4HadronicProcessStore

 In attachement, an example of macro and output
