The low-lying dipole strength of the deformed nucleus Gd-156 was
investigated in the energy region from 3.1 MeV to 6.2 MeV using the
method of nuclear resonance fluorescence (NRF). The NRF experiments were
performed at the Darmstadt High Intensity Photon Setup (DHIPS) at
Technische Universitat Darmstadt using unpolarized continuous-energy
bremsstrahlung and at the High-Intensity gamma-ray Source (HI gamma S)
at Duke University using quasi-monoenergetic and linearly-polarized
photon beams. The combination of both experiments allows to separate
electric and magnetic contributions and to determine absolute transition
strengths for individual excited states as well as averaged quantities
over narrow excitation energy regions. The investigated energy regions
cover the region of the scissors mode as well as the low-energy part of
the Pygmy Dipole Resonance. This is the first experiment where both of
these excitation modes as well as the region in between has been
successfully studied in a deformed heavy nucleus using the NRF method.
