Abstract: The dipole response of the proton-magic nucleus was previously investigated with electromagnetic and hadronic probes. Different responses were observed revealing the so-called isospin splitting of the Pygmy Dipole Resonance (PDR). Here we present the results of a new study of using inelastic proton scattering at low energies to test an additional probe possibly exciting states of the PDR. The response to the new probe as well as the -decay behavior of excited states were studied. The (p,p’) experiment was performed at using the combined spectroscopy setup SONIC@HORUS at the Tandem accelerator of the University of Cologne. Proton- coincidences were recorded, enabling a state-to-state analysis due to the excellent energy resolution for both particles and rays. states in the PDR region were populated in the present inelastic proton scattering experiment. Many -decay branching ratios could be determined.
