Zusammenfassung
The semi-magic nuclei Ba-138, Ce-140, and Sm-144 have been investigated
in photon scattering experiments up to an excitation energy of about 10
MeV The distribution of the electric dipole strength shows a resonance
like structure at energies between 5.5 and 8 MeV exhausting up to 1\% of
the isovector E1 Energy Weighted Sum Rule. (C) 2002 Elsevier Science
