C191100100010 SAMPLE The targets were 5 cm x 5 cm x 0.181 g/cm2 and 0.354 C191100100011 g/cm2 NE 102 plastic scintillators. C191100100012 DETECTOR (NAICR) Two 7.6 cm x 7.6 cm NaI(Tl) crystals. C191100100013 PART-DET (AR) C191100100014 METHOD (ACTIV,GSPEC,BGCT) The 11C activity, which is 100% C191100100015 beta+ decay to 11B, was measured after bombardment C191100100016 using the a beta+gamma-gamma coincidence technique. C191100100017 Each NaI windowed the 0.511 MeV annihilation C191100100018 photopeak pulses. A gamma-gamma coincidence between C191100100019 the two indicated a beta+ decay in a scintillator. C191100100020 ANALYSIS (DECAY) The beta+, gamma-gamma, and beta+gamma-gamma C191100100021 counts were all multiscaled and fitted to a half-life C191100100022 curve with 11C 1224 sec half-life, and each had a C191100100023 xi2/(degree of freedom) of approximately one.

C191100200005 ERR-ANALYS (DATA-ERR) Uncertainty is solely based on the C191100200006 uncertainty in the ion chamber, beam intensity C191100200007 measurements. Statistical errors are negligible. C191100200008 (ERR-1) 1% dead time for beta+ counting. C191100200009 (ERR-2) 2% Background for NaI gamma-gamma counting.
