Abstract

The energy distribution curves for 2p-core-level photoemission of Fe have been calculated based on a completely relativistic treatment of the core as well as the final states. In accordance with recent experiments, a pronounced dependence on the helicity of the exciting radiation has been found. All features of the experimental spectra could be explained in terms of ground-state properties calculated within the framework of local-spin-density-functional theory. From the results it is concluded that exchange interaction will in general contribute to an appreciable extent to the linewidth of core lines of magnetic systems.
