The Ag target was sandwiched between threeA059200100011 pairs of 3.5 mg/cm2 mylar foils, the innerpair of A059200100012 foils served as forward and backward catchers, and the A059200100013 outer pair of foils were gaurd foils. The pair of A059200100014 foils between each pair of inner and outer foils servedA059200100015 as blank measurements. The two target stacks used forA059200100016 the chemical separations were the same, except threeA059200100017 pairs of 8.7mg/cm2 Al foils (99.99% ) were used insteadA059200100018 of mylar foils. A059200100019 A thermal-neutron activation analysis was performed onA059200100020 the mylar foils at the Tsing-Hua research nuclear A059200100021 reactor, and showed no observable Sc, Mn, Fe, Co, Ni, A059200100022 Ga or As impurities. A059200100023 METHOD (STTA) Two irradiated target foil stacks were subjectedA059200100024 to chemical separations before measuring the activitiesA059200100025 of the reaction products, and another two target foil A059200100026 stacks were measured without chemical processing. A059200100027 (EXTB) The incident beam of 245-MeV 12-C(5+) ions had A059200100028 an intensity of 70 electrical nanoamperes in the targetA059200100029 foils. A059200100030 (BCINT) An electron-suppressed Faraday cup. A059200100031 (ACTIV) Irradiations were between 30 and 60 minutes in A059200100032 length. The charge deposited in the Faraday cup was A059200100033 recorded periodically throughout the bombardments to A059200100034 permit the reconstruction of the beam flux histories. A059200100035 (GSPEC) Gamma-ray spectra of each sample in the energy A059200100036 range between 50 KeV and 2 MeV were taken at several A059200100037 time intervals. A059200100038 (CHSEP) A059200100039 DETECTOR (GELI) A059200100040 ANALYSIS (AREA,DECAY) The peak areas were sorted into decay A059200100041 curves, which were interactively identified on the A059200100042 basis of gamma-ray energy and half-life. A059200100043 CORRECTION For the absolute gamma-ray abundance, chemical yield, A059200100044 and gamma-ray detection efficiency. The beam flux A059200100045 history was used to calculate apparent production crossA059200100046 sections. A059200100047 FACILITY (CYCLO,1USABRK) 88-inch cyclotron.
