C189800100013 SAMPLE Target stacks consisted of 20 microm thick depleted C189800100014 uranium foil sandwiched between five 20 microm thick C189800100015 aluminum foils of high purity (99.999%). C189800100016 METHOD (RCHEM,GSPEC,STTA,ACTIV) Following the irradiation C189800100017 the target and catcher foils were separately C189800100018 dissolved in acid and a radiochemically separated. C189800100019 The disintegration rates of the various nuclides of C189800100020 interest were determined by gamma-ray spectrometry. C189800100021 The product cross section were derived from the data C189800100022 using the relationship between nuclides. C189800100023 DETECTOR (GELI) A calibrated Ge(Li) detector. C189800100024 PART-DET (G) C189800100025 ANALYSIS (PGS) The gamma-spectra were analyzed with the code C189800100026 SAMPO in order to obtain the disintegration rates. C189800100027 ERR-ANALYS (DATA-ERR) The listed uncertainties are larger of the C189800100028 standard deviations from the means. The uncertainties C189800100029 are based on the uncertainties in the C189800100030 gamma-ray counting rates as obtained from SAMPO. C189800100031 (ERR-1,3.,5.) 3-5% in chemical yield determination. C189800100032 (ERR-2) 5% detector efficiency. C189800100033 (ERR-3) 5% target thickness uniformity. C189800100034 MONITOR (13-AL-27(P,X)11-NA-24,,SIG) The beam intensity C189800100035 determination.)
