The stack D062200100010 contained an array of several gold target samples in D062200100011 addition to aluminum and copper foils as beam energy D062200100012 degrader and monitors. Due to the energy loss of the D062200100013 bombarding proton beam, each foil was irradiated at D062200100014 different beam energies, so several experimental D062200100015 points of the reaction cross-section can be obtained D062200100016 for only one irradiation. D062200100017 FACILITY (CYCLO,3EGYCAI) MGC-20 cyclotron in Inshas, Egypt D062200100018 DETECTOR (HPGE) The gamma-ray spectrometer consists of a HPGe- D062200100019 detector of 145 cm3 active volume, Canberra 3106D D062200100020 high voltage power supply, Canberra 2026 spectroscopy D062200100021 amplifier coupled to either a PCA-II or (TRUMP-8192) D062200100022 multi-channel analyzers. The absolute efficiency D062200100023 curves of the detector were determined by the D062200100024 standard 133Ba, 60Co, 152Eu, 154Eu and 155Eu gamma- D062200100025 sources at different source to detector distances D062200100026 ERR-ANALYS (ERR-T) The uncertainties in the measured D062200100027 cross-sections were obtained by taking the square root D062200100028 of the sum of the squares of all the considerable D062200100029 uncertainties: D062200100030 (ERR-1,1.,3.)
