High multipole transitions in NIXS: Valence and hybridization in 4f systems
High multipole transitions in NIXS: Valence and hybridization in 4f systems
Momentum-transfer (q) dependent non-resonant inelastic X-ray scattering measurements were made at the N4, 5 edges for several rare-earth compounds. With increasing q, giant dipole resonances diminish, to be replaced by strong multiplet lines at lower energy transfer. These multiplets result from two different orders of multipole scattering and are distinct …
