Abstract
Prompt \(\gamma \)-ray spectra emitted in fast-neutron induced fission of \(^{239}\)Pu have been recently measured by using the LICORNE directional neutron source at E\(_n\) = 1.8 MeV. The results are used in parallel with the measurements of fast-neutron induced fission of \(^{238}\)U and spontaneous fission of \(^{252}\)Cf to assess the potential of such reactions and observables, in contributing to the understanding of fission. The \(\gamma \)-ray spectra were measured and analyzed under similar conditions, allowing a consistent and robust comparison between the three systems. They are further compared to Monte–Carlo simulations based on two widely-used semi-empirical codes, FREYA and GEF. Differences in the low and high energy portions of the spectrum are interpreted based on simple arguments involving nuclear structure and evaporation effects. The significance and potential of experimental campaigns of this kind, as well as current limitations, are highlighted, together with straightforward but mandatory extensions.
