Monitor foils (natural niobium foils, each 3287400100016 1 mm in thickness, 99.95% purity) of the same 3287400100017 diameter as the tungsten sample were attached in 3287400100018 front of and behind each tungsten sample, which was 3287400100019 wrapped in a pure cadmium foil (1 mm in thickness, 3287400100020 99.95% purity) to reduce the effect of the 3287400100021 180W(n,g)181W reaction induced by thermal neutrons 3287400100022 on the 182W(n,2n)181W reaction. 3287400100023 METHOD (ACTIV) The duration of irradiation varied between 3287400100024 6.4 h and 8.2 h. 3287400100025 DETECTOR (HPGE) A well-calibrated GEM-60P coaxial HPGe ORTEC 3287400100026 detector made in USA (crystal diameter 70.1 mm, 3287400100027 crystal length 72.3 mm) with a relative efficiency of 3287400100028 68% and an energy resolution of 1.69 keV at 1332 keV 3287400100029 for 60Co. The efficiency of the detector was 3287400100030 pre-calibrated using a selected set of gamma-ray 3287400100031 standard sources, which were 241Am, 57Co, 60Co, 109Cd, 3287400100032 133Ba, 137Cs, 152Eu, and 226Ra. The samples were 3287400100033 placed directly at a distance of 9 cm away from the 3287400100034 end cap of the detector. 3287400100035 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3287400100036 DECAY-MON
