Abstract: 
The (n,α) reaction in the radioactive ⁵⁹Ni is of relevance in nuclear astrophysics as ⁵⁹Ni can be considered as the first branching point in the astrophysical s-process. Its relevance in nuclear technology is especially related to material embrittlement in stainless steel. However, there is a discrepancy between available experimental data and the evaluated nuclear data files for this reaction. At the n TOF facility at CERN, a dedicated system based on sCVD diamond diodes was set up to measure the ⁵⁹Ni(n,α)⁵⁶Fe cross section. The results of this measurement, with special emphasis on the dominant resonance at 203 eV, are presented here.
