Abstract
The excitations in the nuclide have been studied in a photon-scattering experiment with monoenergetic and linearly polarized beams from 7 to 11 MeV. More than 40 states have been identified from observed ground-state transitions, revealing the fine structure of the giant resonance with a centroid energy of 9 MeV and a sum strength of 4.17(56) . The result for the total strength and its fragmentation are discussed in the framework of the three-phonon quasiparticle-phonon model.
