A new (n,n'γ) experiment was performed at the Geel Electron LINear Accelerator (GELINA) of the European Commission-Joint Research Center (EC-JRC) to measure high resolution neutron cross-sections on several nickel isotopes. To detect the radiation of interest we made use of the Gamma Array for Inelastic Neutron Scattering (GAINS) spectrometer which consists of twelve HPGe detectors with 100% relative efficiency placed at 110, 125 and 150 degrees relatively to the direction of incoming neutron beam. The incident neutrons, which had energies ranging from 0.5 to 20 MeV, were scattered on a natural nickel target with the following characteristics: areal density 2.661(21) mg/cm^2 and diameter 8.23(3) cm. A fission chamber with 235U deposits was also used for data normalization. We will shortly present the data analysis procedure, the most important experimental particularities and the extracted results: the angle-integrated γ-production cross sections for all the observed transitions coming from the inelastic channel on 58,60,64Ni.
