Abstract

The prompt gamma-ray of 871 keV emitted during the bombardment of steels by 5 MeV alpha particles were used to determine nitrogen by means of the reaction14N(α, pγ)17O. The method is non-destructive, rapid and experimentally simple. It has a sensitivity of about 7 μg·g−1. In the nitrogen concentration range of 101–102 μg·g−1 the relative precision of the method is about 3%. The accuracy of the method compares with that of other nuclear methods.
