Benchmark of the GEF code for fission-fragment yields over an enlarged range in fissioning nucleus mass, excitation energy, and angular momentum

摘要: The GEneral description of Fission observables (GEF) code was developed to produce fission-related nuclear data which are importance for basic and applied physics. investigation the performance GEF is here extended a region in fissioning system mass, charge, excitation energy, angular momentum, as well new observables, that could not be benchmarked so far. More specifically, benefiting from recent innovative measurements, work focuses on fragment mass isotopic distributions fission various heavy actinides, with energies threshold up $\ensuremath{\approx}60\phantom{\rule{0.16em}{0ex}}\mathrm{MeV}$ momenta $\ensuremath{\approx}20\ensuremath{\hbar}$. approach reveals high degree consistency provides reasonable data. physics behind specific discrepancies discussed, emphasis challenging modeling competition between symmetric asymmetric channels. Comparison calculation experiment permits us highlight influence intrinsic properties, their interplay, experimental aspects such excitation-energy resolution. All together points necessity measuring many possible one highest accuracy, proper unfolding involved correlations robust interpretation. has become widely used tool this purpose.
