C189900100011 SAMPLE Targets consisted of a mixture of CsBr (optical grade C189900100012 - 99.9%) and 99.99% pure fine aluminum powder, C189900100013 homogeneously mixed and pressed into pellets. The C189900100014 resulting targets contained 38 to 47% C189900100015 monoisotopically pure 133Cs and had a surface density C189900100016 of 59-131 mg/cm2. C189900100017 DETECTOR (GELI) High resolution nuclear diodes Ge(Li) detector. C189900100018 PART-DET (DG) C189900100019 METHOD (RCHEM,GSPEC,STTA,ACTIV) After irradiation the CsBr C189900100020 pellets and adjacent guard foils were dissolved and C189900100021 cesium and barium fractions were chemically separated C189900100022 and purified by standard radiochemical procedures. C189900100023 All samples prepared in this fashion were assayed by C189900100024 gamma detection using a high resolution Nuclear Diodes C189900100025 Ge(Li) detector. C189900100026 ANALYSIS (PGS) Activity measurements were analyzed using the C189900100027 Brookhaven decay curve analysis program CLSQ. C189900100028 MONITOR (13-AL-27(P,X)11-NA-24,,SIG) The 24Na, from the C189900100029 monitor reaction, was beta counted with an end-window C189900100030 gas flow proportional counter. C189900100031 ERR-ANALYS (DATA-ERR) The uncertainties indicated in Table II are C189900100032 root mean square deviations from the average for C189900100033 replicate determinations. C189900100034 (ERR-SYS) Systematic uncertainties C189900100035 are also listed in the table, they include: C189900100036 (ERR-1) 5% for the monitor reaction beta counting C189900100037 efficiency. C189900100038 (ERR-2) 6% for 24Na cross section. C189900100039 (ERR-3,2.,8.) 2-8% in value of the 24Na disintegration C189900100040 rate. C189900100041 (ERR-4,2.,8.) 2-5% for chemical yield determination. C189900100042 (ERR-5) 6% for Ge(Li) detector efficiency. C189900100043 (ERR-6,1.,10.) 1-10% branching ratio, reliability of thC189900100044 decay scheme data. C189900100045 HISTORY (20120307C) BP C189900100046 (20140418U) SD: Author's name corrected.
