The combined setup SONIC@HORUS [1] at the Cologne tandem accelerator, consisting of 12 Silicon and 14 HPGe detectors, is the central setup for nuclear structure experiments using inelastic scattering of light ions. The coincident measurement of the excitation energy and the decaying γ-rays enables a very selective study of properties of nuclear states.
In a previous experiment it could be shown that the measured p-γ angular distribution of transitions in 94Mo can be reproduced by the distorted wave born approximation (DWBA), enabling a spin and parity assignment for low-spin states. A second (p,p’γ) experiment was performed at the 10 MV FN tandem accelerator in Cologne with the aim to verify the spin and parity determination using the DWBA, and to assign multipolarities of the transitions in the low-energy region in 60Ni by studying intensity ratios for different p-γ angle groups. This contribution will present the current status of the analysis of the 60Ni(p,p’γ) experiment.
