欧州原子核研究機関の中性子飛行時間実験施設n_TOFにおいて、1eVから1MeVの領域におけるThの中性子捕獲断面積を測定した。4keVから1MeVにおいて、4%より良い精度で平均捕獲断面積を導出した。IAEAによる独立な評価値は実験値とよく一致した。

We have measured the neutron capture reaction yield of Th at the neutron tim-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The average capture cross section has been extracted in the energy range from 4 keV up to 1 MeV with an overall accuracy better than 4 %. An independent IAEA evaluation shows good agreement with the data.
