C236700100012 INC-SPECT Approximately 2.5x10**15 protons per minute C236700100013 interacted in the target. C236700100014 DETECTOR (GELI,NAICR,PROPC,SIBAR) C236700100015 SAMPLE Each target consisted of a 51 micro-m thick tantalum C236700100016 foil sandwiched between two stacks of three 25 micro-m C236700100017 aluminum foils C236700100018 METHOD (ACTIV,STTA,CHSEP) Most of the tantalum targets were C236700100019 irradiated for 30 min each in the circulating proton C236700100020 beam of the Brookhaven alternating gradient C236700100021 synchrotron. These irradiations mere typically 5 min inC236700100022 duration, and the alpha radiations of both the C236700100023 upstream and the downstream target pieces were C236700100024 assayed directly with surface-barrier Si detectors C236700100025 after they were punched out. The tantalum foil was C236700100026 dissolved in a platinum crucible containing the C236700100027 appropriate rare-earth carriers and a few ml of C236700100028 concentrated HF. C236700100029 ANALYSIS (DECAY) The decay curves were analyzed by means of C236700100030 the CLSQ program to obtain the end-of-bombardment or C236700100031 time-of-separation activities and their standard C236700100032 deviations.
