【 摘 要 】

Several experimental studies using electromagnetic probes have found an enhancement of electric dipole strength between about 5 and 10 MeV. This phenomenon is usually denoted as Pygmy Dipole Resonance (PDR). The detailed structure of these excitations is still under debate. This manuscript will concentrate on the results of complementary experiments using hadronic probes to populate the PDR. These studies allow a first insight into the origin of the PDR. Finally, the manuscript will shortly discuss plans for future experiments.
