| Popis: | Fast-neutron-capture cross-section data on $^{136}\mathrm{Xe}$ have been measured with the activation method between 0.4 and 14.8 MeV. The cross section was found to be of the order of 1 mb at the eleven energies investigated. This result is important to interpret potential neutron-induced backgrounds in the enriched xenon observatory and KamLAND-Zen neutrinoless double-$\ensuremath{\beta}$ decay searches that use xenon as both source and detector. A high-pressure sphere filled with $^{136}\mathrm{Xe}$ was irradiated with monoenergetic neutrons produced by the reactions ${}^{3}$H($p,n$)${}^{3}$He, ${}^{2}$H($d,n$)${}^{3}$He, and ${}^{3}$H($d,n$)${}^{4}$He. Indium and gold monitor foils were irradiated simultaneously with the $^{136}\mathrm{Xe}$ to determine the incident neutron flux. The activities of the reaction products were measured with high-resolution $\ensuremath{\gamma}$-ray spectroscopy. The present results are compared to predictions from ENDF/B-VII.1 and TENDL-2012. |
