Analytical neutron-capture gamma-ray spectroscopy: Status and prospects
The use of neutron-capture gamma rays for elemental analysis has become an established technique, applicable for the measurement of a list of elements which complements conventional delayed-gamma neutron activation analysis. Three distinct areas of application of the prompt method have been laboratory-based analysis using reactor neutrons, field measurements (especially borehole logging for mineral exploration), and industrial process stream analysis, the latter two using neutron generators or isotopic neutron sources. Continued improvements in detector systems and the increasing availability of clean, high-intensity beams from cold-neutron guide tubes are opening quantitatively and qualitatively new analytical possibilities. Second generation instruments using cold neutrons promise an increase in reaction rate of up to two orders of magnitude. This will increae the productivity of these facilities by a similar factor, and will make the use of capture gamma rays more nearly comparable in sensitivity to conventional neutron activation analysis whenever the sample may be brought to the neutrons.
