Both reactions were measured simultaneously with a set of micromegas detectors. The flight path of 185 m has allowed us to obtain the cross section with high-energy resolution. An accurate description of the resonances has been performed by means of the multilevel multichannel R-matrix code SAMMY. The results show a significantly higher area of the biggest resonance (13.45 keV) than the unique high-resolution (n , alpha) measurement. The new parametrization of the 13.45-keV resonance is similar to that of the unique transmission measurement. This resonance is a matter of research in neutron-capture therapy. The S-33(n, alpha)Si-30 cross section has been studied in previous works because of its role in the production of S-36 in stars, which is currently overproduced in stellar models compared to observations.This work was supported by the Spanish projects FPA2013- 47327-C2-1-R, FPA2016-77689-C2-1-R, J. de Andalucía P11- FQM-8229, and FIS2015-69941-C2-1-P (MINECO-FEDER, EU); the Spanish Association Against Cancer (AECC) (Grant No. PS16163811PORR); and the funding agencies of the participating institutes.application/pdfen-AU© 2018http://creativecommons.org/licenses/by/4.0/201810.1103/PhysRevC.97.0646032019-11-25Creative Commons Attribution 4.0 International license
