C220900100012 SAMPLE (5-B-10,ENR=0.98) The target consisted of a thin 10B C220900100013 layer with approx. 400 mu-g/cm2 nominal thickness, C220900100014 deposited on a piece of tantalum that was thick C220900100015 enough to stop all of the protons. C220900100016 DETECTOR (SCIN) Annihilation photons were registered with two C220900100017 LaBr3 crystal bars (4 in. long and with a 2 x 2 C220900100018 (in.)2 cross sectional area), optically coupled to C220900100019 make a bar with dimensions 2 x 2 x 8 (in.)3 Two 8 in. C220900100020 long LaBr3 detectors were placed outside the chamber C220900100021 at a scattering angle of 90. on the left and the C220900100022 right side of the beam at the distance of 2.5 cm from C220900100023 the target. C220900100024 METHOD (ACTIV) The 10B target was irradiated for 1 h at each C220900100025 of the proton energies . After each irradiation the C220900100026 beam was interrupted and the two coincident 511 keV C220900100027 gamma rays emitted by the activated target were C220900100028 measured for another hour. C220900100029 (COINC) Coincidence between the two detectors was C220900100030 required to measure annihilation gamma quanta. C220900100031 ANALYSIS (DECAY) Number of activated nuclei was determined by C220900100032 analysis of decay 11C curve. C220900100033 ERR-ANALYS (ERR-SYS) Overall systematic uncertainty not included C220900100034 in DATA-ERR C220900100035 (DATA-ERR) Uncertainty from weighted average yields, C220900100036 excluding the 8.6% systematic uncertainty C220900100037 HISTORY (20160206C) Compiled by S.H.
