Systematic studies along isotopic and isotonic chains are fundamental for investigating the properties of the low-lying dipole response of atomic nuclei, and can shed light on, e.g., the effects of shell structure and neutron excess on dipole strength. The semi-magic nickel (Z=28) isotopic chain is ideally suited for a systematic study, because of its four stable, even-even isotopes covering a wide range of N/Z ratios. The dipole response of 58Ni, 60Ni, and 64Ni has already been studied in (γ, γ’) experiments [1-4], making the investigation of 62Ni one of the last missing steps to complete the systematics. Therefore, a (γ, γ’) bremsstrahlung experiment on 62Ni up to a maximum photon energy of Emax = 8.7 MeV was performed at the γELBE facility at the Helmholtz-Zentrum Dresden-Rossendorf [5]. First results of this experiment will be presented. This work has been supported by the BMBF (05P21PKEN9).
