Neutron capture cross section of 232 Th measured at the n TOF facility at CERN in the unresolved resonance region up to 1 MeV

Description

We have measured the neutron capture reaction yield of 232Th at the neutron time-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. The average cross section has been expressed in terms of average resonance parameters using the partial waves =0, 1, and 2.
