Kurzbeschreibung (Abstract)
The Pygmy Dipole Resonance (PDR) is the dominating electric dipole excitation below and around the particle separation threshold and exhausts only a few percent of the energy-weighted sum rule. Nevertheless, it may have some impact on reaction rates in nucleosynthesis processes. Therefore, investigations to get more insights in this excitation mode are crucial. A common approach to study the PDR of atomic nuclei is the Nuclear Resonance Fluorescence method (NRF) which bases on real-photon scattering. Absolute cross sections, spin and parity quantum numbers are determined in a model-independent way if suited experimental setups are used. In general, there are two complementary NRF experiments which are presented in this paper.
