Energy-Differential Measurement of the &sup(nat)C(n,p) and &sup(nat)C(n,d) Reactions at the n_TOF Facility at CERN / P.Zugec, V.Furman, [a.o.]. – Text : electronic // Physical Review C. – 2026. – Vol. 113, No. 4. – P. 044621. – URL: https://doi.org/10.1103/fkfd-ctqq. – Bibliogr.: 67.

Energy-differential cross section of the &sup(nat)C⁡(𝑛,𝑝) and &*sup(nat)C ⁡(𝑛,𝑑) reactions was measured at the neutron time-of-flight facility n_TOF at CERN. The measurement was performed in the first experimental area (EAR1; flight path of 182.5 m). Two position-sensitive Δ⁢𝐸−𝐸 silicon telescopes were used. Two naturally occurring carbon isotopes, *1*2C and *1*3C , contribute to the reactions on natural carbon, with the (n,p) reaction threshold at 13.7 MeV and the (n,d) threshold at 14.9 MeV (determined by the *1*2C isotope for both reactions). This paper provides the details of the analysis leading to the final results published previously as a Letter. The cross-section results are reported up to 25 MeV. During the data analysis the population of the excited states in the daughter nuclei *1*1B , *1*2B , and *1*3B had to be considered, requiring the adoption of the branching ratios and angular distributions of the emitted particles from an external source of information. talys-2.0 calculations were used as the main source and an in-depth analysis of the model-related uncertainties was performed. The n_TOF results are largely inconsistent with the major evaluation libraries. On the other hand, an unexpected agreement is found with talys-2.0 calculations. Specifically, the obtained cross section for the (n,p) reaction is significantly higher than in the available evaluations, fully supporting the earlier finding from an integral measurement at n_TOF.
