182W(n, 2n) 181W cross-section data from threshold to 15 MeV

Measurements of the ¹⁸²W(n, 2n) ¹⁸¹Wcross section have been performed in the neutron energy range between 8 and 15 MeV using the activation technique. Such data are needed to help interpret results of laser shots at the National Ignition Facility using a new deuterium-tritium capsule design, featuring a high-Z inner shell, with tungsten as the favored material, and an outer shellmade of a low-Z material. Our data are in very good agreement with the previous data of Frehaut et al. (Technical Report No. 6447, Centre d’Etudes Nucleaires, Saclay, 2016), which are based on a different technique, and are in fair agreement with the ENDF/B-VIII.0 and the JEFF-3.3 evaluations.
