Spectra taken with an Fe-57 O002600100013 target indicated no sharp levels near the Co-56 AAS. O002600100014 The 0.33% Fe-58 component cannot produced a detectable O002600100015 neutron group except possibly for its IAS transition O002600100016 which would lie beside the Fe-56 IAS group. O002600100017 DETECTOR (SCIN).Two 2.54-cm*20-cm Ne-224 liquid scintillation O002600100018 detectors were placed side by side in a earthen- O002600100019 shielded bunker for these longer-flight-path O002600100020 measurements.The 9-m measurements utilized three O002600100021 similar detectors in concrete shields arranged so that O002600100022 data for three angles were obtained simultaneously. O002600100023 FACILITY (CYCLO,1USACLU).The measurements were made with the O002600100024 University of Colorado rotating-beam neutron time-of- O002600100025 flight spectrometer. O002600100026 COMMENT New system employs neutron detectors at fixed, O002600100027 well-shielded positions and varies the angle of O002600100028 incidence of the beam upon the target to obtained an O002600100029 angular distribution.Initial data were obtained at 9 m O002600100030 flight path where Gaussian unfolding procedures were O002600100031 necessary to extract the area of the AAS peak at O002600100032 1.45 MeV from that of the neighboring 1.72 MeV level.
