Abstract
54Fe and 57 Fe are stable iron isotopes, which play an important role in the nucleosynthesis of the slow neutron capture process (s process). In addition, these nuclei are present in many structural materials, and therefore, the knowledge of their neutron capture cross sections is of importance for reactor design studies.
This contribution summarizes the results of the (n, γ) cross sections of these two isotopes in the resolved resonance region. The experiment was carried out at the CERN n TOF facility using the Pulse-Height Weighting Technique in combination with an experimental set-up optmized for reducing neutron induced backgrounds.
