Abstract
In 2010 we investigated the applicability of the current k (0) and k (0)-fission factors for the determination of the n(U-235)/n(U-238) isotopic ratio in multi-elemental samples containing uranium. An overestimation 3-4 % was observed in our determinations when employing the recommended 2003 k (0)-literature. After a recalibration of all our laboratory instruments, a 3 % overestimation was still observed in this work when employing this nuclear data. Therefore we aimed at the experimental re-determination of these composite nuclear constants in order to enhance the reliability of the isotopic ratio determination method and the accuracy of our data-filtering algorithms. New k (0)-fission factors are given for 7 nuclides that are not currently present in the 2012 k (0)-database. Several additional k (0) factors are introduced for some nuclides in this library. Our k (0) results are also compared with those recently reported by Blaauw et al.
