Measurement of the *3*5Cl(n,p)*3*5S Cross-Section at the CERN n_TOF Facility from Subthermal Energy to 120 keV / M.A.Martinez-Canadas, V.Furman, Y.Kopatch, [a.o.]. – Text: electronic // The European Physical Journal A. – 2026. – Vol. 62, No. 5. – P. 90. – URL: https://doi.org/10.1140/epja/s10050-026-01826-3. – Bibliogr.: 35.
The *3*5Cl(n, p)*3*5S reaction plays a key role in neutron dosimetry for Boron Neutron Capture Therapy, in the synthesis of the isotope *3*6S, whose astrophysical origin remains unresolved, and in the design of next-generation molten-salt reactors. Its relevance has motivated its inclusion in the High Priority Request List (HPRL) of NEA. The goal of this work is to determine the *3*5Cl(n, p)*3*5S cross-section from thermal energy to 120 keV for the first time ever in a single measurement, thus reducing systematic uncertainties related to the normalization to the thermal value. This had been a subject of concern in previous evaluations of this reaction. We made use of the Time-of-Flight technique with microMEGAS detectors at Experimental Area 2 (EAR-2) of n_TOF facility at CERN. The *1*0B *7Li and *2*3*5U(n, f) reactions were used as references. Rutherford Back-scattering Spectrometry was performed at Centro Nacional de Aceleradores (CNA) in Sevilla, in order to accurately determine the masses of the irradiated samples. We obtained a thermal cross-section of barns. The 1/v energy dependence of the cross-section is observed up to the first resonance at 0.398 keV, the resonances up to 120 keV are analyzed and resonance parameters extracted using SAMMY. Maxwellian Averaged Cross-Section (MACS) was calculated for &sub(B)T=30 keV from 1 to 100 keV, and lower values compared to estimations from ENDF were found, e.g., 1.07 ± 0.20 mb at keV. The thermal cross-section and first two resonances are in agreement with the latest evaluation in ENDF/B-VIII.1, while remarkably lower resonance strengths were found for high energy resonances.
