The Energy Dependence of the Electric Dipole Strength in Heavy Nuclei

Junghans, A. R.; Beyer, R.; Grosse, E.; Rusev, G.; Schwengner, R.; Wagner, A.

We investigate on the basis of new photon scattering measurements and photoneutron and average neutron resonance capture data how well Lorentzians adjusted to photoneutron data in the giant dipole resonances give a good description of the photon strength also below the neutron threshold. If deformation effects are properly taken into account it is verified that down to about 4 MeV for various nuclei with A £¾ 80 the previously employed differentiation between deformed and non-deformed nuclei is no longer necessary.
