The probability for nuclei to capture neutrons reveals sharp peaks, so-called "resonances," which occur at neutron energies specific for each element. These resonances are very suitable for identifying and quantifying elements in objects and materials. They are the basis of an analytical method called "Neutron-Resonance-Capture-Analysis" (NRCA). This is a fully non-destructive method applicable to almost all stable isotopes, which determines the bulk elemental composition, and does not require
