I'm trying to extract specific isotopic cross sections from the G4NDL set, mainly for plotting.
When I use the G4HadronicProcessStore::GetInelasticCrossSectionPerIsotope(...) method it always returns 0, even if the PerAtom method returns a value. As far as I understand both methods, the latter should be the weighted sum of all natural occuring isotope cross sections?
I tried this by adding a column to the Hadr00 example.
if(fVerbose>0) G4cout << std::setw(12) << xs/barn; xs = store->GetInelasticCrossSectionPerAtom(particle,e,elm,mat); xtot += xs; if(fVerbose>0) G4cout << " " << std::setw(12) << xs/barn; xs = store->GetInelasticCrossSectionPerIsotope(particle,e,13,27);
It always returns 0 (see attached file). Similarly for other elements/isotopes.
What am I'm doing wrong?
