L022700100012 INC-SOURCE (ARAD) Monoenergetic photon beam from the L022700100013 annihilation in flight of fast positrons. L022700100014 DETECTOR (BF3,NAICR) The neutron detector, which surrounded L022700100015 the lower portion of the cryostat, consisted of 48 L022700100016 BF3 proportional counters imbedded in a cylindrical L022700100017 polyethylene moderator. 8-in. x 8-in. NaI gamma L022700100018 spectrometer with a known response function. L022700100019 CORRECTION All of the cross sections presented have been L022700100020 corrected for: (a) neutron multiplicity, (b) neutrons L022700100021 produced by bremsstrahlung photons, (c) the variation L022700100022 of detector efficiency with neutron energy, and (d) L022700100023 neutrons produced by sources other than the holmium L022700100024 target. The error bars on the data reflect all of L022700100025 these corrections except (c) those attributed to L022700100026 variations in the neutron detector efficiency.
