Consistency of nuclear data in the fundamental databases for use in the k0 method

In 2003, an overview paper was published with recommended nuclear data for use in the k0-standardization of instrumental neutron activation analysis. At the same time, these data were made available by the International Union of Pure and Applied Chemistry in the form of a downloadable database.In the process of verifying the consistency of the nuclear data inside the k0-IAEA software with these published fundamental databases of recommended k0-data, a variety of inconsistencies within and between the two datasets came to light.In this paper, we present the inconsistencies and resolve them where possible.Experimental verification of k0 values for selected uranium fission products, as performed in Delft, is also presented.
