C294100100012 Pilot-B plastic neutron detectors. C294100100013 SAMPLE The targets were made by cracking methyl iodide onto C294100100014 hot 0.005-in. -thick tantalum disks. The target C294100100015 thicknesses, determined by measuring the yield of the C294100100016 13C(p,gamma)14N reaction over the narrow resonance at C294100100017 Ep= 1.75 MeV, ranged 20 to 80 mu-g/cm2. C294100100018 (6-C-13,ENR=0.55) C294100100019 METHOD (COINC) C294100100020 CORRECTION Corrections to the pulse-height spectra were made for C294100100021 background counts arising from accidental coincidences C294100100022 (0.5% contribution) and true coincidences due to C294100100023 indirect neutrons from the target (2% contribution). C294100100024 A small correction to the asymmetry was also made in C294100100025 several of the measurements for incomplete precession C294100100026 of the neutron spins.
