C235000100011 METHOD (ACTIV,CHSEP) After irradiations, radiochemical C235000100012 separations, developed from standard precipitation, C235000100013 solvent extraction, and ion-exchange techniques, were C235000100014 performed. C235000100015 ERR-ANALYS (DATA-ERR) The uncertainty associated with each cross C235000100016 section value represents the total experimental C235000100017 uncertainty calculated from the associated systematic C235000100018 and random uncertainties. The systematic C235000100019 uncertainties considered were the counter C235000100020 efficiencies, decay schemes, monitor cross section C235000100021 value, minor target isotopic impurity corrections, C235000100022 and summing corrections. The sources of random C235000100023 uncertainty were counting statistics, decay curve C235000100024 analyses, chemical yield determinations, timing, and C235000100025 target misalignment.
