TODO - The cross section of the Au197(n,2n)Au196 reaction has been determined at six energies ranging from 15.3-20.9 MeV by means of the activation technique, relative to the Al27(n,α)Na24 reaction. Quasimonoenergetic neutron beams were produced via the H3(d,n)He4 reaction at the 5.5 MV Tandem T11/25 accelerator laboratory of NCSR "Demokritos". After the irradiations, the induced γ-ray activity of the target and reference foils was measured with high-resolution HPGe detectors. The cross section for the high spin isomeric state (12-) was determined along with the sum of the ground (2-), the first (5+), and second (12-) isomeric states. Theoretical calculations were carried out with the codes empire 3.2.2 and talys 1.8. Optimum input parameters were chosen in such a way as to simultaneously reproduce several experimental reaction channel cross sections in a satisfactory way, namely the (n,elastic), (n,2n), (n,3n), (n,p), (n,α), and (n,total) ones. © 2018 American Physical Society.
