Phys. Rev. B 66, 045106 (2002) [7 pages]Resonant inelastic x-ray scattering at the lanthanum L3 edgeReceived 4 January 2002; published 18 July 2002 Pre-edge structure, not resolved in La L3 x-ray-absorption spectra, has been observed in LaS and in two La-Ni intermetallics using resonant inelastic x-ray scattering (RIXS). The 2p3d RIXS data were successfully simulated using a schematic representation of the densities of unoccupied states. It is concluded that the pre-edge structure is largely dominated by dipole transitions involving hybridized 4f states. No such hybridization occurs for LaF3. In this case multiplet calculations performed within an atomic model clearly indicate that pre-edge structure observed in both the x-ray-absorption spectrum and the 2p3d RIXS data originates from quadrupole transitions. © 2002 The American Physical Society URL:
