title: Influence of source coherence on x-ray absorption spectroscopy.
abstract: Core-level x-ray absorption spectroscopy measurements have been performed at the L3,2 edges of Fe and Co thin films. The degree of source coherence was varied using soft x rays from five different beam lines. We observe an increase of the L edge resonance intensities relative to the continuum states which we propose is due to the presence of transverse coherence in the exciting radiation.
