摘要：
The dipole response of the proton-magic nucleus Sn-124 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 Sn-124 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 Sn-124(p,p'gamma) experiment was performed at Ep = 15 MeV 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. J = 1 states in the PDR region were populated in the present inelastic proton scattering experiment. Many gamma -decay branching ratios could be determined.
