Isomeric cross sections of fast-neutron induced reactions on 197Au
Abstract
Recent accurate data obtained for the isomeric cross section of the 197Au(n,2n) reaction provide a valuable opportunity to consider the question of the effective moment of inertia of the nucleus within a local consistent model analysis of all available reaction data for the 197Au target nucleus. Thus, a definite proof of a moment of inertia equal to that of the rigid--body has been obtained for 196Au nucleus while an inference of the half rigid--body value is suggested for the 194Ir nucleus. The usefulness of further measurements at incident energies up to 40 MeV has also been proved.
