Resonant Inverse Photoelectron Spectroscopy (RIPES) and X-ray Emission Spectroscopy (XES) have been used to probe the electronic structure of Uranium Dioxide, UO2. From these variants of soft x-ray spectroscopy, the nature of the main and satellite features at the U4d5/2 edge can be ascertained. This leads to important insights into the multi-electronic correlations underlying the ubiquitous satellite features of UO2 and implications for future experiments with Pu.
