Abstract : Activation analyses of samples containing unknown elements is usually difficult due to the presence of many lines each of which may belong to any of a number of elements. The purpose of this report is to present a method for the interpretation of spectral data based on the identification of prominent lines characteristic of the thermal neutron activation of the elements in which all isotopes of a particular element are considered collectively, rather than individually as has been customary. Since only the prominent lines (relative intensity = or > 0.5) belonging to the spectrum of an activated isotope are considered, much of the element-assignment-ambiguity introduced by low intensity photons is eliminated. At the heart of the procedure is a catalog of prominent line spectra for the elements. Each catalog page provides a schematic spectrum of the prominent decay photon lines produced by thermal neutron activation of the stable isotopes of a particular element.
