The energies of gamma rays produced by either fast or captured neutrons are unique to each element. The elements in the explosive of a buried mine are carbon, nitrogen, oxygen, and hydrogen. This paper analyzes data taken on buried explosive simulants. The gamma detector was a high purity germanium crystal with excellent energy resolution and the neutrons were produced by a compact deuterium-tritium accelerator, which generated 14 MeV neutrons. The gamma rays from the explosive must be separated from the large soil background. The utility for explosive detection of each element is separately analyzed in detail. Issues of normalization and gain shifts are also addressed.
