Abstract  

In this paper neutron resonance capture analysis (NRCA) is explored as a new method to analyse the elemental composition of materials and objects using a pulsed beam of epithermal neutrons and a time-of-flight system to recognize resonances of isotopes in the energy range from about 1 to 10 keV. Some test experiments have been carried out with bronze artefacts. Advantages, as compared to instrumental neutron activation analysis (INAA), are the low activation of the objects and the direct availability of results after the measurement.
