Layers of A089500100023 488, 408 and 451 mug/cm**2 U238F(4) were evaporated onA089500100024 backing foils of 42 mug/cm**2 carbon and subsequently A089500100025 covered with carbon layers of 10, in a few cases also A089500100026 of 20 mug/cm**2. A089500100027 In parts 2 and 3 we used metallic uranium targets. A089500100028 Metallic U-238 electrodes with a U-235 depletion to A089500100029 0.2% were the starting material. The thickness of the A089500100030 uranium layers was about 300 mug/cm**2. A089500100031 In all parts of the experiment a carbon foil of A089500100032 30 mug/cm**2 thickness was placed at a distance of A089500100033 125 mm behind the target.

The clover detector was separated from A089500100045 the SHIP vacuum by a 1mm thick aluminium window. The A089500100046 detector consisted of four Ge crystals, each with a A089500100047 diameter of 50 mm and a length of 70 mm.
