Abstract
A technique has been developed whereby a pulsed, monoenergetic fast ne utron beam is used to determine concentrations of the elements H, C, N and O in small (0.2-1 kg) samples. Organic scintillators detect neutr ons scattered by the sample and pulse height and time-of-flight data r ecorded by the detectors are analysed using the HEPRO program system ( PTB, Braunschweig). Test measurements on compounds of the four element s show that atom fractions and masses may be determined to a few perce nt accuracy. (C) 1998 Elsevier Science B.V. All rights reserved.
