Abstract
The response of a LaCl3:Ce detector has been found to depend upon the hydrogen content of bulk samples in prompt gamma analysis using 14MeV neutron inelastic scattering. The moderation of 14MeV neutrons from hydrogen in the bulk sample produces thermal neutrons around the sample which ultimately excite chlorine capture gamma rays in the LaCl3:Ce detector material. Interference of 6.11MeV chlorine gamma rays from the detector itself with 6.13MeV oxygen gamma rays from the bulk samples makes the intensity of the 6.13MeV oxygen gamma ray peak relatively insensitive to variations in oxygen concentration. The strong dependence of the 1.95MeV doublet chlorine gamma ray yield on hydrogen content of the bulk samples confirms fast neutron moderation from hydrogen in the bulk samples as a major source of production of thermal neutrons and chlorine gamma rays in the LaCl3:Ce detector material.Despite their poor oxygen detection capabilities, these detectors have nonetheless excellent detection capabilities for hydrogen and carbon in benzene, butyl alcohol, propanol, propanic acid, and formic acid bulk samples using 14MeV neutron inelastic scattering.
