Description
In the last years it has become obvious that a combination of different experimental approaches is necessary to understand the structure of electric dipole strengths in atomic nuclei (see, e.g., refs. [1-12]) and to be able compare it to theoretical models. Due to the high level density in the energy region of interest, a selective excitation mechanism selective spectroscopy are key requirements of the experiments. In this talk the most recent results of experiments using bremsstrahlung and monoenergetic photon beams, medium-energy and low-energy hadronic probes will be discussed.
