Abstract = {{We present resonant inelastic x-ray scattering spectra from La metal
   La2CuO4 and LaF3. Monochromatic photon excitation with energy across the
   La 3d(5/2) (M-5) threshold was used and the valence scattering was
   monitored at selected incoming energies. The spectra vs the outgoing
   photon energy show the elastic peak, the 5p - 3d(5/2) decay peak and, in
   between, a feature due to charge transfer excitation. This brings an
   electron from the ligand to the lanthanum 4f states (in the case of
   La2CuO4 and LaF3) and results from a charge fluctuation from 4f(o) to
   4f(1) occupation in the case of La metal. The energy transferred to the
   solid when this process occurs is remarkably different in the three
   cases and correlates with the difference in the electronegativity with
   the lanthanum neighbors, The present approach allows us to reveal
   features that are completely hidden in the x-ray absorption spectra.}},
