We wish to make the following correction to the published paper [1].
On page 6 of reference [1], it states that “The ratio of the N4:N5 intensities is 9.” This statement is incorrect. The N4:N5 ratio is 1/9, as can be easily gleaned from an examination of Figure 5. The inversion of the ratio negates the supporting, but not essential, argument based upon the UO2 N4,5 XES. The great intensity at the N5 edge is due to an extension of the resonance observed in inverse photoelectron spectroscopy, as discussed in Reference 33 of the article and the references therein. A separate examination of the UO2 N4 region suggests a cross sectional enhancement of the 5f contribution relative to the 6p contribution, as will be discussed in a future publication.
