Photon-scattering experiments with bremsstrahlung were performed on
92Mo, 98Mo and 100Mo at electron energies up to 13.2 MeV.
The
measurements were carried out at the new bremsstrahlung facility of the
Rossendorf ELBE accelerator. The highest end-point energies are above the
neutron-separation energies of the three isotopes and allow the
determination
of the dipole strengths below the giant dipole resonance. The decay to
intermediate levels was estimated with the constant-temperature
level-density
model and the dipole-strength distributions were reconstructed. The
obtained
results are completed with data from neutron-scattering experiments [1]
and compared with predictions of RPA calculations.
