Light-ion production in 175 MeV quasi-monoenergetic neutron-induced reactions on iron and bismuth and comparison with INCL4 calculations
Résumé
importance for several different applications, notably accelerator-driven incineration of nuclear waste. The
Medley setup located at The Svedberg Laboratory in Uppsala, Sweden was used for a series of measurements
of p, d, t, 3He and alpha particle production from 175 MeV neutrons on various target nuclei. Medley uses an
arrangement of 8 detector telescopes placed at angles from 20 to 160 degrees relative to the neutron beam to
register event and discriminate among the particle types. Using the ΔE-ΔE-E technique we were able to
measure double-differential cross sections over a wide dynamic range. This paper describes the experimental
set-up, summarizes the data analysis and reports on recent changes in the previously reported preliminary data
set on bismuth. Experimental data are compared with several different model calculations. In this paper we
specifically compare the experimental results with INCL4 intra-nuclear cascade calculations combined with
the ABLA de-excitation code. Considering the fact that the experimental data are obtained at an energy
normally considered too low for intra-nuclear cascade calculations, we do find some systematic difference but
generally reasonable agreement.
