D058400100015 Each stack contained several properly prepared samples D058400100016 of natural Y2O3 (89Y = 100%) as well as aluminium and D058400100017 copper foils as absorbers and monitors, respectively. D058400100018 The thickness of the prepared Y2O3 layers ranged D058400100019 between 2 and 5 mg/cm2. They were homogeneous and D058400100020 mechanically stable. D058400100021 Each target was covered by a 10 um thick and 16 mm in D058400100022 diam. Al foil. D058400100023 Thus each sample consisted of an Al-Y2O3-Al sandwich. D058400100024 MONITOR Cu monitor foils were included in the stack to D058400100025 calculate the actual beam current during the D058400100026 irradiation. D058400100027 DETECTOR (HPGE) HPGe detector, Canberra 3106D high voltage D058400100028 power supply and Canberra 2026 spectroscopy amplifierD058400100029 coupled to a (TRUMP-8192) multichannel analyzer. D058400100030 The measured energy resolution was 2.0 keV for the D058400100031 gamma-ray of energy 1332.5 keV. D058400100032 To reduce the background, the detector was surrounded D058400100033 by a cylindrical lead shield with an inner layer of D058400100034 Cu to prevent gamma ray scattering. D058400100035 ERR-ANALYS (ERR-T) 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) Table 2 of Radiochim.Acta 97(2009)467 D058400100041 HISTORY (20091007C) SD D058400100042 (20110816U) On.
