The nucleus 94Mo was investigated using a powerful combination of a photon scattering experiment, an off-beam \gamma \gamma coincidence study following the \beta + decay of 94mTc, and the fusion-evaporation reaction 91Zr(\alpha ,n)94Mo. We identified the one-phonon 2+ Mixed-Symmetry (MS) state and two-phonon MS states in the nucleus 94Mo from the measurement of absolute M1 and E2 transition strengths. These strengths were determined from photon scattering cross sections, Doppler shifts, branching ratios, and E2/M1 mixing ratios. The experimental results are in reasonable agreement with the interacting boson model.
