C304100100012 DETECTOR (HPGE) Two HPGe crystal spectrometers with lead C304100100013 shielding. C304100100014 METHOD (ACTIV) All activations were conducted using ion- C304100100015 beams. An electro-static analyzer and a bending C304100100016 magnet on the low energy side facilitated the C304100100017 selection of the ion beam to be accelerated. On the C304100100018 high-energy side, an analyzing magnet allowed for the C304100100019 selection of the charge state,and thus beam energy. C304100100020 Targets were placed in vacuum at the end of the C304100100021 electrically-isolated +15 degrees beamline. Electrons C304100100022 ejected from the target were suppressed both C304100100023 geometrically and magnetically with two permanent C304100100024 magnets near the target. C304100100025 ANALYSIS (DECAY) A system of equations was prepared describing C304100100026 gamma emission as a function of activity at end-of- C304100100027 bombardment (EOB). This system of equations included C304100100028 parent-daughter relationships, decay branching and C304100100029 constants, gamma-ray intensities, spectra collection C304100100030 time and collection duration. These equations were C304100100031 fit to the efficiency-corrected data using a C304100100032 Monte-Carlo technique for error estimation purposes. C304100100033 In this way, decay corrected activities at the EOB wereC304100100034 determined. The activities for each radioisotope C304100100035 observed at EOB were then used to calculate C304100100036 production rates. C304100100037 ERR-ANALYS (DATA-ERR) The cross-section errors were based on the C304100100038 uncertainties in target thicknesses, beam current, C304100100039 counting statistics (area under curve and background), C304100100040 and detector efficiency. The detector efficiency C304100100041 uncertainties were based on the accuracy of the C304100100042 calibration sources, counting statistics, and fits. C304100100043 CORRECTION The efficiency-corrected data using a Monte-Carlo C304100100044 technique for error estimation purposes result in C304100100045 decay corrected activities.
