Abstract A series of measurements has been made to establish the photon transition intensities of 14N(n, γ) 15N to an accuracy suitable for use as a calibration standard. By observing all transitions possible, use could be made of the decay scheme to constrain a function devised to represent the detector efficiency. The parameters of the model were estimated by requiring an intensity balance for each level. This procedure yielded absolute intensities with an average precision of 1%. The quality of the results permitted detection of intensity anomalies which were resolved by a reassessment of the decay scheme. The energies of the associated transitions, although well known, were reestablished. In addition there are some levels which were observed for the first time with this reaction. An ancillary experiment was conducted to explore an apparent energy anomaly. The results showed that significant energy discrepancies can arise when small changes in the geometry of the radiation source occur.
