The effects of neutron scattering by hydrogen within targets for cold neutron prompt γ-ray activation analysis (CNPGAA) have been characterized. For most targets studied, the probability for neutron absorption, and hence CNPGAA sensitivities (counts·s−1·mg−1), decrease with increasing H content and with target thickness. Comparisons with results from thermal neutron PGAA indicate that the effects of cold neutron scattering differ from those of thermal neutron scattering. CNPGAA sensitivities for “l/v” nuclides show similar sensitivity decreases, while Sm sensitivities show smaller decreases.
