Elemental analysis by gamma-ray detection following inelastic neutron scattering

A method of elemental analysis based on the detection of prompt γ-rays produced by the inelastic scattering of fast monoenergetic neutrons has been investigated. Time-of-flight discrimination techniques and the use of Ge(Li) detectors provide significant advances over previous studies. This method is multielemental, non-destructive, and essentially free of interferences and matrix effects. Sample analysis is rapid and selective excitation of various elements is possible. Many elements have been examined by this technique and minimum detection limits have been established. This method has been applied to the analysis of metal alloys.
