D443600100010 Lesker company (part no. EJTSIO2451A2), D443600100011 DETECTOR (HPGE) D443600100012 METHOD (ACTIV) To determine the resonance yield (Yres) six D443600100013 measurements were carried out above the resonance D443600100014 energy at Ep=427 or 433 keV, to obtain the total D443600100015 yield (Ytot) and two measurements below the resonance D443600100016 at Ep=396 and 404 keV to determine the yield D443600100017 without the resonance region (Yoff). D443600100018 The applied beam energies were in the range between D443600100019 Ep=394-433 keV, below and above the resonance energy. D443600100020 The cyclic activation method was used, meaning the D443600100021 irradiation and decay counting phases being repeated D443600100022 many times. The duration of the irradiation in one D443600100023 cycle was 5 min, followed by a 15 min beam-off period D443600100024 for decay and gamma-counting. D443600100025 Thin Al layer was evaporated on the targets to drain D443600100026 the electric charge deposited by the proton beam. D443600100027 The thickness of the Al layer was about 2 keV at D443600100028 Ep=416.9 keV resonance energy. D443600100029 ERR-ANALYS (ERR-1) Effective stopping power 4.5 %.
