The T-Mo target 3272900100014 thickness is 0.566 mg/cm2 and an active zone diameter 3272900100015 of 1.2 cm. 3272900100016 DETECTOR (HPGE) The crystal geometry is 70.1 x 72.3 mm in 3272900100017 diameter and length. The relative efficiency is about 3272900100018 68%, and energy resolution is 1.69 keV at 1332 keV 3272900100019 gamma ray from Co-60. The efficiency of the detector 3272900100020 was pre-calibrated using various standard gamma 3272900100021 sources, which were Co-57, Co-60, Cd-109, Ba-133, 3272900100022 Cs-137, Eu-152, Am-241 and Ra-226. 3272900100023 (SIBAR) The Au-Si surface barrier detector used in 3272900100024 the 135-deg accompanying alpha-particle tube was 110 3272900100025 cm from the target. 3272900100026 METHOD (ACTIV) The sample was irradiated and lasted around 3272900100027 24 hours with a yield around 3 to 4E10 n/(4pi*s). The 3272900100028 sample groups were placed at 0, 90 or 135 degree 3272900100029 relative to the beam direction and centered about the 3272900100030 T-Mo target at distances of around 4 cm. During 3272900100031 irradiation, the neutron flux was monitored by 3272900100032 accompanying alpha particles so that corrections 3272900100033 could be made for small variations in the yield. 3272900100034 MONITOR 1(13-AL-27(N,A)11-NA-24,,SIG) 3272900100035 2(41-NB-93(N,2N)41-NB-92-M,,SIG) 3272900100036 DECAY-MON 1(11-NA-24,14.959HR,DG,1368.6,1.00) 3272900100037 2(41-NB-92-M,10.15D,DG,934.4,0.9907) ) 3272900100038 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,1990) 3272900100039 CORRECTION The self-absorption of the sample at a given gamma 3272900100040 energy, in the counting geometry, and the coincidence 3272900100041 sum effect of cascade gamma rays in the investigated 3272900100042 nuclide were corrected. 3272900100043 ERR-ANALYS (ERR-T) Total uncertainty 3272900100044 (ERR-S,0.1,13.1) Counting statistics 0.1-13.1% 3272900100045 (ERR-1,2.,4.)
