Abstract
A new method to determine experimentally the isotopic abundance of uranium has been developed by measuring the ratios of selected fission product pairs. The relationship between the 235U abundance and the ratios of 14 MeV neutron-induced fission products, which are N(3892Sr)/N(44105Ru) and N(3892Sr)/N(53135I), have been obtained. The results of 4 test samples show that the relative deviations between the measured and the reference 235U abundances are less than ±3%.
