Antihelium inelastic cross section

Dear all
I have a question about how to get inelastic cross sections for antihelium-4. Taking Hadr09 example as a basis, I use anti-alpha particles as a projectile and protons as a target for [1.E-3, 1.E4] (GeV) energy range. In /src/HadronicGenerator.cc i ask for the inelastic cross sections as follows:

//Get cross section
  static bool una_vez = true;
  if(una_vez){
    G4cout << "####################################" << G4endl;
    //G4cout << "4Hebar + p" << G4endl;
    G4cout << "4Hebar + Fe" << G4endl;
    G4cout << "####################################" << G4endl;
    G4cout << "projectileEnergy [GeV]" << " " << "Inelastic cross section [mbarn]" <<G4endl; //LFGC022025
    una_vez = false;
  }
  
  G4DynamicParticle * dynParticle = new G4DynamicParticle( projectileDefinition, projectileDirection, projectileEnergy );
  const G4Element* element = targetMaterial->GetElement(0);
  //G4cout << "####################" << G4endl;
  //G4cout << "Inelastic cross section = " <<theProcess->GetElementCrossSection(dynParticle, element, targetMaterial)*1e25 << " [mbarn]" << G4endl;
  //G4cout << "####################" << G4endl;
  G4cout << projectileEnergy/CLHEP::GeV << "  " << theProcess->GetElementCrossSection(dynParticle, element, targetMaterial)*1e25 << G4endl; //LFGC 022025

  return aChange;
}

Is this correct?, it works well for antideuteron and antihelium-3 cases, but not for 4He-bar because the values are much lower (see attached figure below). I hope you can help me
Thank you very much
