With Cd 2242600100035 60 ml of solution was poured into polyethylene 2242600100036 capsule (0.7 mm wall thickness, 1 mm outer diam., 2242600100037 40 mm outer length), which in turn was set in cylin- 2242600100038 drical Cd capsule (1 mm wall thickness, 22 mm outer 2242600100039 diam, 63 mm outer length). Without Cd the solution 2242600100040 was diluted 1/10 with distilled water and poured into 2242600100041 another polyethilene capsule. 2242600100042 Two additional potassium-iodine samples were used to 2242600100043 measure the quantity of 127I atoms in 127I-129I 2242600100044 solution. 2242600100045 ERR-ANALYS (ERR-T) Total error equal to Quadratic Sum of Stat. 2242600100046 And Systematic Errors 2242600100047 (ERR-S) Statistical error For Gamma-Rays of 128I 2242600100048 (ERR-1) Error in the Gamma-Ray Peak Efficiency 2242600100049 (ERR-2) Error in the Detection efficiency 2242600100050 (ERR-3) Error in the Neutron Flux Measurement 2242600100051 (ERR-4) Error Due to Variation of Neutron Flux 2242600100052 (ERR-5) Error in the emission Probability of the 2242600100053 443 KeV Gamma-Ray Per Decay 2242600100054 (ERR-6) Error in Measurement of the Amount of 127I 2242600100055 (ERR-7) Error in the Measurement of the Weight of 2242600100056 Target 2242600100057 (ERR-8) Statistical error For Gamma-Rays of Monitor 2242600100058 Wires, Au and Co 2242600100059 STATUS (TABLE) Data are Taken from Table 7 of Main Reference 2242600100060 HISTORY (19991202C) + + Compiled by S.M. + + 2242600100061 (20000503U) . .
