Abstract
INDIRECT methods of measuring the abundance of deuterium involve chemical preparation and very careful purification of the samples1,2. This disadvantage and possible source of error is avoided in a method based on the 2D(γ,n)1H reaction for photon energies greater than 2.2 MeV. The number of neutrons emitted from the sample in conjunction with a suitable γ-ray source is a measure of the amount of deuterium present, and, under constant experimental conditions, a direct comparison with deuterium standards may be made.
