Abstract

We present experimental evidence that the newly discovered multiatom resonant photoemission effect can be observed via secondary decay processes of the primary core hole: Auger electron emission, from ${Fe}_{2} O_{3},$ where the O ${KL}_{23} L_{23}$ intensity is enhanced by 90% when $h ν$ is tuned to the Fe $L_{3}$ edge, and fluorescent x-ray emission, from MnO, where the O $K α$ fluorescence intensity shows an enhancement of more than 100% at the Mn $L_{3}$ edge when properly corrected for saturation and self-absorption effects.
