Stopping power effects in the determination of14N by a resonance reactionStopping power effects in the determination of14N by a resonance reaction Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-12-021981enThe applicability of the14N(p,p’ γ1)14N nuclear reaction in the determination of the absolute abundance of14N, with a 2% uncertainty, was demonstrated at 4.3 MeV bombarding energy. The fact that almost all of the thick target γ-ray yield resulted from a resonance at Ep=4.0 MeV allowed to consider the necessary stopping-power corrections only at the energy of that resonance. Alternatively, the method was used to obtain the stopping power of 4.0 MeV protons in complex biological materials.http://creativecommons.org/licenses/by/4.0/Journal of Radioanalytical Chemistry63165-71 Xenoulis Alexander C.
