Abstract

A comprehensive compilation of X- and γ-ray emitting isotopes produced by the (n, γ) reaction is reported in this paper for application to instrumental neutron activation analysis (INAA). The X- and γ-ray sensitivities are computed theoretically by a computer code. Interfering photons from isotopes of neighbouring elements are identified by the code and the percentage interference is computed. Additionally an advantage factor (X-ray: γ-ray sensitivity) is computed, which is a figure of merit for X-ray spectroscopy in INAA. Further, mathematical representation of background continua for typical matrices encountered in INAA allow the calculation of elemental detection limits for the X-ray and γ-ray photons.
