Abstract

Recent accurate data obtained for the isomeric cross section of the ¹⁹⁷Au(n, 2n) reaction provides an effective opportunity to consider the question of the effective moment of inertia of the nucleus within a consistent model analysis of all available reaction data for the ¹⁹⁷Au target nucleus. Moreover, since the corresponding model assumptions are better validated by analysis of the data above 20-30 MeV where only several data with large uncertainties are known, the usefulness of further measurements to be performed at large-scale facilities as SPIRAL-2 and n_TOF, for incident energies up to 40 as well as 100 MeV, are underlined.
