Abstract
Photon scattering experiments on the odd, deformed nuclei and provided detailed information on the excitation energies and transition probabilities of low-lying dipole excitations. In the case of the even-even nuclei in addition spins and parities of the excited states could be determined model independently by measuring the angular distributions and the linear polarization of the scattered photons using a Compton polarimeter. The results are compared with the systematics obtained for the neighboring even-even isotopes and in previous photon scattering experiments. Whereas in the odd Dy isotopes a concentration of dipole strength is observed, which fits nicely into the systematics of the orbital M1 mode, the dipole strength in is completely fragmented into about 90 transitions.
