Measurement and analysis of the 241Am(n,γ ) cross section with liquid scintillator detectors using time-of-flight spectroscopy at the n_TOF facility at CERN

| Tóm tắt: | The 241Am(n,γ ) cross section has been measured at the n_TOF facility at CERN using deuterated benzene liquid
scintillators, commonly known as C6D6 detectors, and time-of-flight spectrometry. The results in the resolved
resonance range bring new constraints to evaluations below 150 eV, and the energy upper limit was extended from 150 to 320 eV with a total of 172 new resonances not present in current evaluations. The thermal capture
cross section was found to be σth = 678 ± 68 b, which is in good agreement with evaluations and most previous
measurements. The capture cross section in the unresolved resonance region was extracted in the remaining
energy range up to 150 keV, and found to be larger than current evaluations and previous measurements. |
