Resonant Raman x-ray scattering on molybdenum was studied using a Mo-anode x-ray tube and a LiF crystal monochromator. Beside the usual resonant Raman peak corresponding to the fluorescent $K\alpha$ lines, another peak with a smaller energy loss was found. It is attributed to resonant Raman scattering with a final-state $M$-shell vacancy corresponding to the fluorescent $K\beta$ lines. Both contributions are shown to be independent of the scattering angle. Absolute cross sections have been determined and compared with theoretical predictions.
