The Hanford site 1239400100009 https://en.Wikipedia.org/wiki/Hanford Site is currently1239400100010 operated by Pacific Northwest National Laboratory. 1239400100011 FACILITY (SPECC,1USAHAN) 1239400100012 DETECTOR (PROPC) 1239400100013 METHOD (BGCT) A gold foil was irradiated in the 0.10 eV 1239400100014 neutron beam directly behind the 235U foil whose 1239400100015 fission counting rate was observed. The absolute 1239400100016 activity of the gold foil was determined by 1239400100017 comparison beta counting in a proportional counter 1239400100018 with an identical gold foil which was irradiated in a 1239400100019 thermal neutron beam and whose absolute activity was 1239400100020 determined by beta-gamma coincidence counting. The 1239400100021 235U fission cross section at 0.0253 eV is obtained 1239400100022 from the previously determined shape of the fission 1239400100023 cross section and the assumed 197Au capture cross 1239400100024 section. 1239400100025 ERR-ANALYS (ERR-T) Include statistical uncertainty, gold 1239400100026 cross section uncertainty and the weight of the 1239400100027 fission foil uncertainty. 1239400100028 (ERR-S) Statistical analysis uncertainty. 1239400100029 HISTORY (19760804T) Translated from SCISRS. 1239400100030 (19820519A) Converted to reaction formalism. 1239400100031 (20190806A) BP: Updated to new date formats,lower 1239400100032 case. corrections according last EXFOR rules and 1239400100033 Dict.
