The reaction N14(γ,n)N13 has been studied by irradiating dicyandiamide in the X-ray beam of a 25-Mev betatron and measuring the residual activity with a sodium iodide crystal system. The photoneutron cross section shows maxima at 11.7, 13.2, 15.2, 19.5, and 22.8 Mev, the last two being in the giant resonance region. The integrated cross section from threshold to the beginning of the giant resonance region is 1.8 Mev-mb, and this is compared with a recent theoretical prediction. During the course of the experiment, accurate measurements were made of the half-life of N13 and it was found to be 9.93 ± 0.05 minutes.

Resolved resonance evaluation of the 239Pu cross section in the energy range up 4 keV has been carried out with the SAMMY computer code. Existing resolved resonance evaluation such as ENDF/B-VIII.0 and JENDL4 data libraries for 239Pu is limited to 2.5 keV whereas above this energy the unresolved resonance methodology is used. High resolution transmission and fission data taken at the Oak Ridge Electron Linear Accelerator (ORELA) permitted extending the resonance region up to 4 keV. The thermal and average fission cross section values calculated with the resonance parameters derived in the evaluation fall close to that indicated in the suggested IAEA fission standards.
