Measurement of resolved resonances of ²³²Th(n,γ) at the n-TOF facility at CERN

The yield of the neutron capture reaction ²³²Th(n, γ ) has been measured at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture yield for resolved resonances from 1 eV to 4 keV is described and compared to a recent evaluated data set. The resonance parameters were used to assign an orbital momentum to each resonance. A missing level estimator was used to extract the s-wave level spacing of D0 = 17.2 ± 0.9 eV.
