None photonuclear cross sections+isotope production

Hello all,

I am trying to reproduce the photonuclear reaction cross section in the GDR region for Au-197 thus I am using the Hadr03 example for counting the Au196 produced isotopes. I have seen that the class provides the total inelastic cross-sections for all the photonuclear interactions, but how can I access the isotope production cross-section (for example the cross section that corresponds to the reaction Au197(g,n)Au196)?

Does the values in the Isotope Production folder in the G4NDL4.2 provides this information? I have tried to change the cross-section values for the Au-196 but there was no difference in the results.

Regarding these cross-section values (for Au196) I noticed that for example for energy 13.5 MeV the value provided is approximately 200 mb while in EXFOR -for the same energy- the value is around 500 mb. Why is that discrepancy? Could it be a source of understimation for the Au196 production?
