High precision measurement of the radiative capture cross section of $^{238}$U at the n_TOF CERN facility

The importance of improving the accuracy on the capture cross-section of $^{238}$U has been addressed by the Nuclear Energy Agency, since its uncertainty significantly affects the uncertainties of key design parameters for both fast and thermal nuclear reactors. Within the 7th framework programme AN...

Sumario:The importance of improving the accuracy on the capture cross-section of $^{238}$U has been addressed by the Nuclear Energy Agency, since its uncertainty significantly affects the uncertainties of key design parameters for both fast and thermal nuclear reactors. Within the 7th framework programme ANDES of the European Commission three different measurements have been carried out with the aim of providing the $^{238} \text{U(n,}\gamma)$ cross-section with an accuracy which varies from 1 to 5%, depending on the energy range. Hereby the final results of the measurement performed at the n_TOF CERN facility in a wide energy range from 1 eV to 700 keV will be presented.
