We studied the Mo 4d electronic structure of Sr2FeMoO6 using high-energy Mo L3 resonant photoemission. The experimental spectra are in good agreement with modified Becke- Johnson (mBJ) band structure calculations. The energy dependence of the spectra can be ex- plained by the changes in the photoemission cross-sections. The Mo L3 resonant spectrum shows Mo 4d character below the Fermi level and mixed Mo 4d-O 2p character around 8.0 eV. The Mo 4d weight in the resonant spectrum is in good agreement with the calculated interference between the direct and decay terms. The high photon energy used in this study (about 2520 eV) provides a bulk-sensitive determination of the Mo 4d electronic structure.
