After the neutron irradiations, 1325100100017 the target foils were dissolved in the presence of 1325100100018 10-20-mg amounts of carriers for each of the desired 1325100100019 products. The samples were counted on gas-flow beta 1325100100020 proportional counters or NaI(Tl) gamma counters. 1325100100021 MONITOR (39-Y-89(N,2N)39-Y-88,,SIG) Flux monitor. 1325100100022 ERR-ANALYS (DATA-ERR) Data uncertainties given include 1325100100023 uncertainty in counting efficiencies and counting 1325100100024 statistics, and standard deviation.
