a 300 KeV 2076100100017 deuteron beam for 2.9 MeV range. 2076100100018 INC-SOURCE (POLNS,D-D) 2.9 MeV neutrons. 2076100100019 Polarized neutrons with a polarization rate of 15% for 2076100100020 the 2.9 MeV neutrons (at 49 degr. to the deuteron beam)2076100100021 SAMPLE Natural targets 2076100100022 METHOD (TOF,ASSOP) 2076100100023 An associated particle time-of-flight system was used 2076100100024 to provide 2.9MeV neutrons. 2076100100025 Fast neutron polarimeter and CAMAC-PDP11/05 2076100100026 multi-channel analyser data collection system were 2076100100027 used. 2076100100028 The asymmetry in the scattering of polarized neutrons 2076100100029 was determined simultaneously at 3 sct angles,while 2076100100030 adequate monitoring of the N-flux provided to 2076100100031 enable the diff.cs. to be obtained also. 2076100100032 (PHD) Gammas were rejected by pulse-height 2076100100033 discrimination. 2076100100034 DETECTOR (SCIN) Scintillation counters with pulse-shape 2076100100035 discrimination against gamma-rays were used to detect 2076100100036 the scattered neutrons. 2076100100037 Six and twelve cylindrical NE213 liquid scintillators 2076100100038 (152.4mm long,50.8mm diam.) with their axes 2076100100039 perpendicular to the scattering plane were used for 2076100100040 2.9 and 16.1 MeV energy range respectively. 2076100100041 Their containers were made of thin Al and completely 2076100100042 filled with liquid. 2076100100043 Detectors moved in 2 groups of 3 around the scatterer,2076100100044 one group for measuring scattering to the right,the 2076100100045 other to the left.Within each group the angle between 2076100100046 the detectors was fixed at 28 degrees. 2076100100047 The table carrying the sct sample and six detectors 2076100100048 was mounted on a 2-wheeled cradle which could rotate 2076100100049 about an axis joining the n-producing target to the 2076100100050 centre of the sct.sample. 2076100100051 In addition to the 6 detectors,2 neutrons monitors 2076100100052 were required for normalization to determine sct.cs. 2076100100053 One,the collimated beam monitor was a NE213 liquid 2076100100054 scintillator in a glass cell(12.7cm diam,3.8cm thick) 2076100100055 the other a 2mm thick Li-I(eV) crystal scintillation 2076100100056 detector(enriched to 96% Li-6) surrounded by 10 cm 2076100100057 thickness of paraffin wax, was placed near the target.2076100100058 COMMENT Comparison with published optical model calculations. 2076100100059 STATUS (TABLE) Data taken from private communication. 2076100100060 16.1 MeV
