Abstract
Parity quantum numbers of $J=1$ states up to 7 MeV in the region of the Pygmy Dipole Resonance in $^{140}\mathrm{Ce}$ were determined model independently by combining the methods of Nuclear Resonance Fluorescence and Compton polarimetry. For the first time the well-established method of Compton polarimetry was applied at such high energies. The experiment was performed using a fourfold segmented HPGe clover detector for the detection of the scattered photons. For all investigated dipole transitions asymmetries are found which correspond to negative parity of the excited states.
