L024300100010 INC-SOURCE (BRST,KINDT) Pulsed bremsstrahlung (6-, 10-, or 20-nsecL024300100011 duration, 720 Hz) swept clean of electrons and L024300100012 positrons was produced in a 0.51-mm Ta radiator by L024300100013 electrons from the NRC linac. L024300100014 SAMPLE (82-PB-208,ENR=0.91) L024300100015 (82-PB-207,ENR=0.07) The target was a 795-g disk, 15 L024300100016 cm diam by 4.5 mm thick, containing 91% of 208Pb and L024300100017 7% of 207Pb. L024300100018 DETECTOR (SCIN) The neutron detector, a 30-cm-diam by 76-mm- L024300100019 thick disk of plastic scintillator viewed by four L024300100020 photomultipliers, was situated 31.2 m from the L024300100021 photoneutron target at the end of an evacuated flight L024300100022 tube at 90 to the photon beam. L024300100023 METHOD (TOF,COINC) Conventional time-of-flight techniques L024300100024 with time resolution of 0.3 to 0.7 nsec/m. A L024300100025 coincidence between two phototubes constituted an L024300100026 event. To reduce gamma flash, a 1-cm Bi slab was L024300100027 placed in front of the detector.
