Neutron -induced inelastic gamma-production cross sections on Ni-58,Ni-60,Ni-64

This paper reports partial results of a (n, n'gamma) measurement on nickel. The inelastic channel was measured using the Gamma Array for Inelastic Neutron Scattering (GAINS) spectrometer at the 100-m measurement cabin of the Geel Electron Linear Accelerator (GELINA) neutron source of the European Commission's Joint Research Centre (EC-JRC) in Geel, Belgium. Using y spectroscopy, we were able to extract angle integrated production cross sections for several y rays but we report here only the results for the main transition in Ni-58. We discuss however in detail the observed discrepancy between our data and other experiments (especially the work of Voss et al.). We also shortly comment on the quality of the neutron-target optical model potential in describing the inelastic data in this mass region. The calculations were performed using the TALYS 1.9 code in the default settings.
