Abstrakt

Analytical application of the coincidence instrumental neutron activation analysis (NAA) was demonstrated on a sample of the Morávka meteorite (2000). The use of the strongest low-energy coinciding γ-lines of 192Ir has shown a significantly enhanced resolution power of the detection system as well as improved selectivity with respect to the accurate Ir determination compared with conventional single-detector instrumental NAA, even for highly active samples. Comparison of the results with those obtained by similar types of analysis has shown not only a high degree of correspondence, but also highlighted some advantages of the new method.
