Photonuclear reactions are well-suited to provide fundamental spectroscopic quantities of nuclei such as γ-ray transition energies, spin and parity quantum numbers [1]. The present work focuses on the study of the dipole strength distribution, its disentanglement into electric and magnetic contributions, and the decay behavior of excited states of ⁹⁶Mo. For that purpose, Nuclear Resonance Fluorescence (NRF) experiments were performed at the High Intensity Gamma-ray Source (HIγS) with linearly-polarized, quasi-monochromatic photon beams to assign parity quantum numbers and determine branching ratios of observed states. In this contribution, first results will be presented.
