D058400100013 Each stack contained several properly prepared samples D058400100014 of natural Y2O3 (89Y = 100%) as well as aluminum and D058400100015 copper foils as absorbers and monitors, respectively. D058400100016 The thickness of the prepared Y2O3 layers ranged D058400100017 between 2 and 5 mg/cm2. They were homogeneous and D058400100018 mechanically stable. D058400100019 Each target was covered by a 10 um thick and 16 mm in D058400100020 diam. Al foil. D058400100021 Thus each sample consisted of an Al-Y2O3-Al sandwich. D058400100022 DETECTOR (HPGE) Canberra 3106D high voltage power supply and D058400100023 Canberra 2026 spectroscopy amplifier coupled to a D058400100024 (TRUMP-8192) multichannel analyzer. The measured D058400100025 energy resolution was 2.0 keV for the gamma-ray of D058400100026 energy 1332.5 keV. To reduce the background, the D058400100027 detector was surrounded by a cylindrical lead shield D058400100028 with an inner layer of Cu to prevent gamma ray D058400100029 scattering. D058400100030 METHOD (ACTIV,STTA) Several stacks were irradiated by a D058400100031 proton beam of current 200 nA and energy 18 MeV. D058400100032 MONITOR Cu monitor foils were included in the stack to D058400100033 calculate the actual beam current during the D058400100034 irradiation. D058400100035 ERR-ANALYS (DATA-ERR) The total uncertainty in the measured cross D058400100036 section was in the range of 10% - 14%, depending on: D058400100037 * the detector efficiency, D058400100038 * counting statistics and D058400100039 * beam current D058400100040 STATUS (TABLE,,H.M.Omara+,J,RCA,97,467,2009) Table 2 D058400100041 HISTORY (20091007C) SD D058400100042 (20110816U) On.
