Background: The N14(n,p)C14 reaction is of interest in neutron capture therapy, where nitrogen-related dose the main component due to low-energy neutrons, and astrophysics, N14 acts as a poison s process. Several discrepancies remain between existing data obtained partial energy ranges: thermal energy, keV region, resonance region. Purpose: We aim measure cross section from region single measurement for first time, including characterization resonances, provide calculations Maxwellian averaged sections (MACS). Method: apply time-of-flight technique at Experimental Area 2 (EAR-2) (n_TOF) facility CERN. B10(n,α)Li7 U235(n,f) reactions are used references. Two detection systems run simultaneously, one on beam another off beam. Resonances described with R-matrix code sammy. Results: was measured subthermal 800 keV, resolving two resonances (at 492.7 644 keV). A (1.809±0.045 b) that lower than most recent measurements by slightly more standard deviation, but line ENDF/B-VIII.0 JEFF-3.3 evaluations. 1/v dependence confirmed up tens energy. low tail suggested evaluated values, while overall strength agrees Conclusions: Our has allowed determination N14(n,p) over wide range time. have high accuracy (2.5%) these calculate MACS kT=5 kT=100 keV.8 MoreReceived 15 December 2022Accepted 22 May 2023DOI:https://doi.org/10.1103/PhysRevC.107.064617Published American Physical Society under terms Creative Commons Attribution 4.0 International license.
