Question Energy distribution of product nuclei - nuclei have zero energy

Hello! I study the particle (neutron, muons) interactions with matter (rock, carbon). I simulate the production of given isotopes (tritium, helium) in thin target and calculate the cross sections. I also calculate the energy distribution of product nuclei. But a major number of product nuclei has the zero energy after production. I use reference physics list FTF_BERT_HP, QGSP_BIC_HP, QBBC and the results are similar. The latest version of Geant4 is used.

The fragment of SteppingAction class

G4ParticleDefinition* PDefinition = aStep->GetTrack()->GetDefinition(); G4String particleType = PDefinition->GetParticleType();

if (particleType == "nucleus")
{
   G4int i;
   if ((PDefinition->GetAtomicNumber()) == Z
      && (PDefinition->GetAtomicMass()) == A)
   {
     G4double particleKineticEnergy = aStep->GetTrack()->GetKineticEnergy();	
     runaction->addNucleus(i, particleKineticEnergy);
     aStep->GetTrack()->SetTrackStatus(fStopAndKill);
   }
}
