Abstract:	The (n,alpha) 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,alpha)56Fe cross section. The results of this measurement, with special emphasis on the dominant resonance at 203 eV, are presented here.
