Description michel.maire 2014-03-10 15:30:15 CET 
In SteppingAction :

   const G4StepPoint* endPoint = aStep->GetPostStepPoint();
   const G4VProcess* process   = endPoint->GetProcessDefinedStep();
   G4HadronicProcess* hproc = (G4HadronicProcess*) process;
   const G4Isotope* target = hproc->GetTargetIsotope();

 In case of neutronHP, it returns 0

  Tatsumi said :
Since v9.6, NeutronHP re-set target nucleus in hadronic process by the nucleus which HP system selected. 
So by getting the information in proper timing, then you should get correct information about the target.
