Multiatom resonant photoemission observed via secondary processes: Auger decay and x-ray fluorescence

We present experimental evidence that the newly discovered multiatom resona nt photoemission effect can be observed via secondary decay processes of th e primary core hole: Auger electron emission, from Fe2O3, where the O KL23L u23 intensity is enhanced by 90% when h v is tuned to the Fe L-3 edge, and fluorescent x-ray emission, from MnO, where the O K alpha fluorescence inte nsity shows an enhancement of more than 100% at the Mn L-3 edge when proper ly corrected for saturation and self-absorption effects.
