Systematic studies within isotopic and isotonic chains are essential to investigate the properties of the low-lying dipole strength below and around the neutron-separation threshold. The nickel (Z = 28) isotopic chain is a well-suited candidate for this purpose because it consists of four stable, even-even isotopes covering a large range of N/Z ratios. Since photons just transfer small angular momenta, (γ,γ′) experiments are ideally suited to study the dipole response in atomic nuclei [1]. The isotopes 58,60,64Ni have already been measured in (γ,γ’) experiments [2-5]. To complete the systematics, 62Ni was investigated using energetically continuous bremsstrahlung with a maximal photon energy of Emax=8.7 MeV at the γELBE facility [6].
First results of this experiment will be presented.
