Results of total cross section measurements for 197Au in the neutron energy region from 4 to 108 keV at GELINA
Transmission measurements have been performed to determine the total cross section for neutron induced reactions with 197Au in the energy region from 4 keV to 108 keV. The experiments were carried out at a 50 m measurement station of the time-of-flight facility GELINA using a 6Li glass scintillator. The average total cross section as a function of neutron energy was derived after correcting the observed average transmission for cross section fluctuations due to resonance structures. The results have been compared with literature data and with the total cross section resulting from a dispersive coupled channel optical model potential. The neutron strength function for s-wave neutrons and an orbital independent scattering radius, together with their covariance matrix, have been derived in the neutron energy region between 4 keV and 108 keV through a parameterization of the total cross section based on a nuclear reaction theory.
