Neutron beam filtered through 3276200100012 monocrystalline silicon, the cross-section with 8 cm 3276200100013 in diameter. 3276200100014 SAMPLE (92-U-235,ENR=0.902) Isotopic composition of the 3276200100015 sample are 234U (1.1%), 235U (90.2%), 236U (0.3%) and 3276200100016 238U (8.4%). The thick uranium with 16 mm in 3276200100017 diameter and 0.4-0.8 g/cm2 thick was wrapped by pure 3276200100018 aluminium foil with 5 mg/cm2 thick. The thin standard 3276200100019 uranium with 16 mm in diameter and 0.3-0.4 mg/cm2 3276200100020 thick was electrodeposited on the platinum foil with 3276200100021 0.10-0.15 mm thick. 3276200100022 DETECTOR (HPGE) The volume of P-type coaxial HPGe detector is 3276200100023 110 cm3. For gamma energy 1332.5 keV the gamma-energy 3276200100024 resolution FWHM is 1.8 keV. The distance between 3276200100025 detector and sample can be adjusted. At a distance of 3276200100026 31.6 cm, the detection efficiency was calibrated 3276200100027 relatively using Eu-152, and was calibrated 3276200100028 absolutely using various standard gamma sources, 3276200100029 which were Mn-54, Co-57, Zn-65, Cd-109 and Cs-137. 3276200100030 The ratio of detection efficiency between distance of 3276200100031 1.3 cm and 31.6 cm, was mensurated using Cr-51, Mn-54, 3276200100032 Zn-65, Zr-95, Ru-103, Cs-137, Ba-140, Ce-141 and 3276200100033 Ce-144. The uncertainty of efficiency is less than 2% 3276200100034 at 1.3 cm distance. 3276200100035 (FISCH) Double-fission chamber were used to measure 3276200100036 the absolute fission rate. 3276200100037 METHOD (ABSFY,FPGAM) 3276200100038 ANALYSIS Decay gamma spectrum area were determined with SPAN 3276200100039 code. 3276200100040 CORRECTION (1) gamma self-absorbtion for thick sample. 3276200100041 (2) geometry. 3276200100042 (3) neutron scattering from the wall of fission 3276200100043 chamber. 3276200100044 ERR-ANALYS (DATA-ERR) Absolute uncertainty of measurement. 3276200100045 (ERR-1,,2.0) Uncertainty of efficiency of HPGe is 3276200100046 less than 2.0%. 3276200100047 STATUS (TABLE) Data taken from Table 2 of Atom. Ener. Sci. 3276200100048 and Tech.,34(S1) 170,2000.
