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. 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. s paper, we present the inconsistencies and resolve them where possible. mental verification of k0 values for selected uranium fission products, as performed in Delft, is also presented.
