The thickness of all measured Zr foils F152000100014 amounted to 15.0+-1.5 mu-m. Aluminum (8.4+-0.5 mu-m) F152000100015 and copper (4.95+-0.10 mu-m) foils were used as beam F152000100016 monitors. F152000100017 DETECTOR (HPGE) ORTEC GEM 35P4 high purity germanium detector F152000100018 with energy resolution of 850 eV for the 122 keV line F152000100019 and 1.8 keV for the 1330 keV line was used. F152000100020 METHOD (STTA,EDEG,GSPEC) Aluminum foils with thickness F152000100021 21.84+-0.11 mu-m and 43.7+-0.8 mu-m were used as F152000100022 degraders. F152000100023 (ACTIV) Irradiation was carried out for 30 min. AverageF152000100024 current was 228 nA. F152000100025 ADD-RES The thick target yield of 90Nb was calculated based on F152000100026 the measured cross-sections. For the energy range F152000100027 60.5->46 MeV the yield of 90Nb is about 36 MBq/(mu-A*h)F152000100028 An additional 4 MBq/(mu-A*h) 90Nb was obtained during F152000100029 irradiation of 90Mo (19.6 MBq/(mu*A*h)), it was F152000100030 calculated for EOB+ 12 h.
