C237800100012 DETECTOR (NAICR,SCIN) 75-mm thick x 75-mm diameter NaI(Tl) C237800100013 scintillator. C237800100014 SAMPLE The targets were 3.2-mm thick by 38-mm diameter disks C237800100015 of Pilot B plastic scintillator containing 91.6% C237800100016 carbon by weight. No correction was made for the C237800100017 1.11% 13C content of the carbon; that is, the results C237800100018 given in this paper technically apply to natural C237800100019 carbon. C237800100020 METHOD (ACTIV,COINC) After each irradiation, the target was C237800100021 transported to the counting room. The 11C positrons C237800100022 were self-detected by the plastic scintillator, and C237800100023 the annihilation quanta were detected in the NaI(Tl) C237800100024 detector which had an electronic window set to C237800100025 include only 511-keV photopeak pulses. Each sample C237800100026 was counted for at least three half-lives using C237800100027 standard beta-gamma coincidence circuitry. C237800100028 ANALYSIS (DECAY) The data were fitted to a one-component C237800100029 exponential with a 20.4-min half-life using the CLSQ C237800100030 decay code. No significant deviations were observed C237800100031 from the 20.4-min half-life. C237800100032 ERR-ANALYS (DATA-ERR) To obtain cross section uncertainty the C237800100033 EOB activity (disintegrations per minute), total C237800100034 fluence, and coincidence losses were added in C237800100035 quadratures. C237800100036 CORRECTION Accidental coincidence corrections for a time- C237800100037 structured beam.
