Absolute efficiency determined with publish-1082600100014 ed data for the cross sections of protons on B-11, 1082600100015 C-12, and Y-89. 1082600100016 Proton recoil detector used to confirm accuracy of 1082600100017 monitor. 1082600100018 MONITOR Neutron flux measured using known cross sections for 1082600100019 protons on tritium, correcting for tritium purity and 1082600100020 beam heating. 1082600100021 METHOD (TOF) Time-of-flight. Pulse height spectra normalized 1082600100022 to integrated beam current. Measurements made at 90 1082600100023 degrees with and without calcium sample. Data points 1082600100024 averaged over three channels to smooth out statistical1082600100025 fluctuations and integrated over 4 pi. 1082600100026 CORRECTION Corrected for background, DEADTIME, neutron attenuation1082600100027 in sample, and angular variation of neutron flux over 1082600100028 sample. 1082600100029 ERR-ANALYS (DATA-ERR) Typical overall uncertainty is +-20 percent.1082600100030 Poor statistics at 18.2-MeV makes uncertainty greater.1082600100031 STATUS (APRVD) Approved by D.M.Drake, 79/9/6. 1082600100032 Data correspond to figs. 2-5 in Nucl.Phys.A231,29,1974 1082600100033 HISTORY (19790417C) 1082600100034 (20200104U) OS.
