D638200100010 A high-purity (99.5%) metallic form of natural-zinc D638200100011 foil (86-um thickness) with isotopic composition of D638200100012 64Zn (49.17%), 66Zn (27.73%), 67Zn (4.04%), D638200100013 68Zn (18.48%) and 70Zn (0.61%) was used as a target. D638200100014 Natural copper of purity > 99% and 103.45-um thicknessD638200100015 and natural aluminium of purity > 99% and 108-um D638200100016 thicknesses were used as monitor foils as well as D638200100017 proton beam energy degrader. D638200100018 DETECTOR (HPGE) The gamma-ray activities were measured with a D638200100019 pre-calibrated HPGe detector connected to a PC based D638200100020 4096 channel analyzer. D638200100021 The energy resolution of the detector was 1.8 keV at D638200100022 the photo-peak of 1332.5 keV gamma-line of 60Co. D638200100023 The dead time of detector always kept less than 5%. D638200100024 METHOD (ACTIV,STTA) The stack was irradiated for 10 min with D638200100025 proton beam energy of 20 MeV and beam current of D638200100026 a 100 nA. D638200100027 The irradiated stack was cooled for about 1.5 h.
