The transformation was O034900100015 ascertained using alpha-spectrometry and direct O034900100016 weighing. The average thickness of the 236-U-oxideO034900100017 layer was 100 mug/cm**2 and that of the Np-237-oxideO034900100018 layer 110 mug/cm**2. The thickness variations wereO034900100019 within 3%. The average thicknesses were determined by O034900100020 weighing.
