We report the first observation by momentum-resolved resonant inelastic X-ray scattering of charge excitations in an iron-based superconductor and its parent compound, PrFeAsO$$_{0.7}$$ and PrFeAsO respectively, with two main results. First, using calculations based on a 16 band $$dp$$ model, we show that the energy of the lowest-lying excitations, identified as $$dd$$ interband transitions of dominant $$xz$$, $$yz$$ orbital character, exhibits a dramatic dependence on electron correlation. This enables us to estimate the Coulomb repulsion $$U$$ and Hund's coupling $$J$$, and to highlight the role played by $$J$$ in these peculiar orbital-dependent electron correlation effects. Second, we show that short-range antiferromagnetic correlations, which are a prerequisite to the occurrence of these excitations at the $$Gamma$$ point, are still present in the superconducting state.
