Abstract. Electromagnetic dipole-strength distributions up to the particle separation energies are studied for the stable even–even nuclides ^{92,94,96,98,100}Mo in photon-scattering experiments at the superconducting electron accelerator ELBE of the Forschungszentrum Dresden-Rossendorf. The influence of inelastic transitions to low-lying excited states has been corrected by a simulation of γ cascades using a statistical model. After corrections for branching ratios of ground-state transitions, the photon-scattering cross sections smoothly connect to data obtained from (γ, n) reactions. With the newly determined electromagnetic dipole response of nuclei well below the particle separation energies, the parametrization of the isovector giant dipole resonance is done with improved precision.
