MEASUREMENT OF IMPURITY EFFECTS IN THE MASS SPECTROMETER ISOTOPIC ANALYSIS OF URANIUM HEXAFLUORIDE
Tests to determine the extent of the isotopic analysis errors resulting from ion beam distrotion by gaseous impurities in uranium hexafluoride samples were run on several mass spectrometers. Mixtures of uranium hexafluoride with five other gases were compared to pure uranium hexafluoride of identical isotopic composition, noting the bias of the measured ratios of mole ratios from unity. Nitrogen caused a greater bias than the other gases tested; ten per cent nitrogen can cause a bias of more than one per cent in the ratio of pure to impure sample mole ratios. (auth)
