Resonances at 429 keV and 897 keV in the 15 N(p, ac) 12 C reaction were investigated for depth profiling nitrogen in materials containing nitrogen isotopes in natural abundances. Both resonances exhibit identical sensitivity, however the resonance at 897 keV is prone to interferences from light elem
