Abstract

 In neutron activation analysis based on the k0 standardization method (k0-INAA), the k0-factor is a combination of nuclear constants and it was measured by experiments. It plays an important role in the accuracy of k0-INAA method. Therefore, it is necessary to measure  the k0-factors in many different neutron sources and compare the results. In this paper, the k0- factors to gold of manganese (k0,Au­(Mn)), cadmium ((k0,Au­(Cd)), Chromium ((k0,Au­(Cr)), Zinc ((k0,Au­(Zn)), Arsenic ((k0,Au­(As)), Vanadium ((k0,Au­(V)) by neutron activation with the Am-Be isotope neutron source were measured. The comparision between our results and the results of Decorter et. al. showed relative differences of less than twenty percents. Among which, our most accurate result was found in (ko,Au(Mn)) with only 1.18 percents relative difference.
