Selective excitation of the Pygmy dipole resonance in ¹²⁰Sn via the (d,pγ)-reaction

The excitation of states belonging to the Pygmy Dipole Resonance (PDR) by a single-neutron transfer-reaction was investigated in ¹²⁰Sn, using a ¹¹⁹Sn(d,pγ)-experiment and the combined setup SONIC rate at HORUS at the 10 MV Tandem accelerator in Cologne. The setup consisting of 14 HPGe and 6 ΔE-E silicon telescope detectors for the coincident detection of γ-rays and charged particles, respectively, enables an offline selection of excitation and deexcitation channels. First results show that dipole states in the PDR region, i.e. 5 MeV to 9 MeV, could be excited by the reaction. These dipole states were identified as PDR states by comparison with data from a Nuclear Resonance Fluorescence experiment. The contribution will present the experiment and principles of the data analysis needed to select transitions from or to J^π=1^- states. Using results from the experiment, features of the PDR are discussed, including possible particle-hole configurations.
