Background gating with 1075400100011 continuous background from foreground subtraction 1075400100012 utilized. Energy of neutron beam determined from 1075400100013 existing tables for the neutron source reactions. 1075400100014 Absolute neutron flux determined by cross calibration 1075400100015 between the long counter and a simplified proton- 1075400100016 recoil telescope. 1075400100017 DETECTOR (GELI,NAICR) 34-cc coaxial germanium-lithium detector 1075400100018 surrounded by a NaI(Tl) annulus, lead shield, and a 1075400100019 paraffin-lithium carbonate shield. Tungsten-iron 1075400100020 shadow bar used. Full energy peak efficiency measured 1075400100021 with calibrated radioisotopes. 1075400100022 (LONGC) Hansen-McKibben long counter using polyethylene1075400100023 instead of paraffin as a shield. 1075400100024 MONITOR (1-H-1(N,EL)1-H-1,,SIG) 1075400100025 CORRECTION Corrected for detector efficiency, gamma self- 1075400100026 absorption, anisotropic neutron flux, single and 1075400100027 multiple neutron scattering in sample. 1075400100028 ERR-ANALYS (ERR-T) Total uncertainty, includes systematic 1075400100029 uncertainties, following, added to statistical error. 1075400100030 Systematic uncertainties are: 1075400100031 (ERR-1) efficiency of detector 1075400100032 (ERR-2) neutron flux determination 1075400100033 (ERR-3) geometry factors 1075400100034 (ERR-4) neutron anisotropy 1075400100035 (ERR-5) neutron attenuation 1075400100036 (ERR-6) gamma-ray attenuation 1075400100037 STATUS (TABLE) Data taken from tables in thesis. 1075400100038 HISTORY (19790410C) 1075400100039 (20091109A) VM:Updated to new date formats,lower case. 1075400100040 BIB updates. 1075400100041 (20140528D) SD: Subents 002-009 deleted - duplication 1075400100042 with 12690002-005.
