“…The energy of these neutrons was, in order, 14.8, 14.4, 14.1, and 13.5 MeV. An uncertainty of 0.2 MeV for the neutron energy at 5 cm was assessed based on a sample evaluation and the d + beam diameter (4 mm) [38]. This uncertainty value is consistent with the Table 2.…”

“…The initial strategy made use of the cross-section ratios of the reactions of 93 Nb((n, 2n)) 92m Nb and 90 Zr((n, 2n)) 89m+g Zr [37]. Another strategy made use of the expression from our previous work [38]. The energy of these neutrons was, in order, 14.8, 14.4, 14.1, and 13.5 MeV.…”

“…There were no interfering gamma rays from Na in the NaBr sample. Table 3 presents a summary of the γ -ray, half-lives, and intensities employed in the analysis [39]. The detection efficiency of the HPGe detector was obtained using the 25 gamma lines of the standard sources 133 Ba, 137 Cs, 152 Eu, and 226 Ra.…”

Measurement of the cross-sections of 79Br(n,2n)78Br, 81Br(n,p)81mSe, 81Br(n,α)78As, and 79Br(n,α)76As reactions was carried out at specific neutron energies precisely 13.5±0.2, 14.1±0.2, 14.4±0.2, and 14.8±0.2 MeV relative to the standard 93Nb(n,2n)92mNb and 27Al(n,α)24Na reference reactions using offline γ-ray spectrometry and neutron activation. The monoenergetic neutrons were generated at the China Academy of Engineering Physics, via a 3H(d,n)4He reaction using a K-400 Neutron Generator equipped with a solid 3H-Ti based target. The activity of reaction produce was obtained utilizing a high-purity germanium detector. The cross-sections of the (n,2n), (n,p), and (n,α) reactions on the bromine isotopes were conducted in the 13–15 MeV neutron energy range. The covariance analysis approach was employed for a thorough inspection of any uncertainties within the measured cross-section data. Discussion and comparison of the observed outcome were carried out with previously published data, in particular with the results of the JENDL-4.0, JEFF-3.3, TENDL-2019, and ENDF/B-VIII.0 data libraries, along with the theoretical excitation function curve derived by employed the TALYS-1.95 program. Improved cross-section restrictions for the investigated processes in the 13–15 MeV neutron energy range will be furnished by the current findings, which will help to raise the caliber of the associated databases. Furthermore, the parameters of the pertinent nuclear reaction models can be verified using this data.

In this study, the cross-sections of the 129Xe(n,n‘)129mXe and 131Xe(n,n’)131mXe reactions were measured for the first time within the energy range 13.5–15.0 MeV based on the 27Al(n,α)24Na monitor reaction cross-section. The experiment employed high-purity, high-pressure, and highly enriched 129,131Xe isotope gas as the target sample. This study marks the first instance in which the measured cross-sections, corresponding correlation matrices, and associated uncertainties are provided. The TALYS-1.96 software was employed to obtain theoretical calculations, allowing for a comparison with experimental and evaluation results. The present study aids in understanding 129Xe(n,n‘)129mXe and 131Xe(n,n’)131mXe cross-sections within 14 MeV regions, where the energy dependence exhibits relatively gradual changes and significant discrepancies between nuclear data libraries have been identified.
