Understanding the hybridization due to orbital overlap in solids allows justification for adjusting electron correlation and hopping integral under the Hubbard model. This work links spatial-overlap-driven to energetic-overlap-driven hybridization from perovskite oxides by resonant inelastic X-ray scattering at La N4,5 edges.
