C004400100010 METHOD (LRASY,DSCAT) C004400100011 DETECTOR (COIN,SCIN,SCIN) High pressure gas scintillator at 17 C004400100012 atmospheres with a mixture of 90% helium and 10% C004400100013 Xenon in cylindrical stainless steel cup 5 cm diameterC004400100014 by 7 cm long coupled to an EMI 6255B photomultiplier. C004400100015 This scintillator was in coincidence with two liquid C004400100016 scintillators, p-terphenyl in xylene. C004400100017 CORRECTION Multiple scattering and asymmetry due to the variation C004400100018 of neutron intensity over the angle subtended by the C004400100019 scatterer were considered to be negligible. C004400100020 Geometrical corrections were made. C004400100021 No asymmetries in the apparatus were found within the C004400100022 limits of statistical accuracy.
