Abstract
Photon scattering experiments have been performed an the nuclei Os-190,Os-1 92 in order to investigate low-lying dipole excitations in the energy range E-gamma<4 MeV in nuclei which are transitional between well-deformed rotor s and gamma-soft nuclei. We determined excitation energies, spins, and abso lute photon scattering cross sections. The low-lying dipole strength in the se even-even nuclei is highly fragmented. [S0556-2813(99)02104-4].
