Measurement of the 238U(n, γ) cross section up to 80 keV with the Total Absorption Calorimeter at the CERN n_TOF facility

2017

The radiative capture cross section of a highly pure (99.999%), 6.125(2) grams and 9.56(5)×10^−4 atoms/barn areal density 238U sample has been measured with the Total Absorption Calorimeter (TAC) in the 185 m flight path at the CERN neutron time-of-flight facility n_TOF. This measurement is in response to the NEA High Priority Request list, which demands an accuracy in this cross section of less than 3% below 25 keV. These data have undergone careful background subtraction, with special care being given to the background originating from neutrons scattered by the 238U sample. Pileup and dead-time effects have been corrected for. The measured cross section covers an energy range between 0.2 …
