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

Figure 5

Calculated atomic 1s2p RIXS map with 2p XES projection for an isolated Cu²⁺ (3d⁹). Notice the 2p XAS (L_2,3-edge) (dashed red) has only one peak, because only the final state with can be populated. See also Figure 7.3 in Core Level Spectroscopy of Solids [13].
