Abstract  

The measurement of prompt particles from reactions induced by 1.2 MeV deuterons on nitrogen can serve as a rapid method for determining nitrogen in steels in ppm range. With suitable absorbers the energy of the prompt alpha-particles can be reduced to that of the prompt protons and counts from both be integrated over a single energy region. Analyses require between 2 and 100 min. Interference from boron and silicon is discussed.
