The Importance of Atomic Relaxation in Core-Level Spectra for Narrow-Band Systems
In recent years various high energy spectroscopies, such as photo-electron spectroscopy, Auger electron spectroscopy, inverse photoemission and X-ray absorption spectroscopy, have proven to be most useful in probing the electronic structure of narrow-band systems.1 Much of the theoretical work in this connection has started out from the utilization of the impurity Anderson Hamiltonian. One important question in the description of the results from these different techniques is to what extent the same parameters should be obtained for the different experimental situations. For instance, to what extent are the parameters used to describe the spectral shapes modified due to the presence of the core-hole?
