Abstract
We present a method for calculating f-electron photoemission spectra of light rare-earth insulating systems within the filled band Anderson impurity model and starting from a spin doublet ground state. We explore the overall lineshapes of the spectra with respect to the various parameters entering the model. An analytical explanation of the calculated spectra is proposed in the infinitely large Uff limit. Typically, contact can be made with experimental direct photoemission spectra in the case of Ce 2O3 compounds, for exampleKeywords
