1s2p RIXS Calculations for 3d Transition Metal Ions in Octahedral Symmetry

Figure 15

Multielectronic term scheme comparing the 2p XAS and the 1s2p RIXS pathways. The two quadrupole 1s XAS transitions with and symmetry lead to two different intermediate state symmetries. The subsequent dipole decays (2p XES) with symmetry yield multiple 1s2p RIXS final state symmetries. The direct 2p XAS (L_2,3-edge) transition with symmetry can on the other hand only access the symmetry in the final state. Noncontributing states are omitted for clarity.
