Abstract

Strong resonant effects are observed at the Ce $L_{3}$ absorption edge in Ce-Rh compounds, both for the Ce $3 d$ photoemission peaks and the $L_{3} M_{4, 5} N_{4, 5}$ Auger lines. These resonances show unambiguously that interference effects exist in core-level spectroscopies. In mixed-valent compounds, they occur at different photon energies making it possible to unravel the x-ray-absorption profiles. Moreover resonant $L_{3} M_{4, 5} N_{4, 5}$ Raman Auger lines are observed up to 10 eV above the $L_{3}$ absorption-edge jump, showing the strong localization of the core excited state.
