The³³S(n,α)³⁰Si cross section measurement at n_TOF-EAR2 (CERN): From 0.01 eV to the resonance region

Abstract

Abstract. The 33 S(n,α) 30 Si cross section measurement, using 10 B(n,α) as reference, at the n TOF Experimental Area 2 (EAR2) facility at CERN is presented. Data from 0.01 eV to 100 keV are provided and, for the first time, the cross section is measured in the range from 0.01 eV to 10 keV. These data may be used for a future evaluation of the cross section because present evaluations exhibit large discrepancies. The 33 S(n,α) 30 Si reaction is of interest in medical physics because of its possible use as a cooperative target to boron in Neutron Capture Therapy (NCT).
