Abstract
Evidence is given for a configuration dependent hybridization in the spectroscopy of a strongly hybridized compound like CeRh3. This is achieved by comparing the results of 4f inverse photoemission and Ce 3d core level spectroscopies to the predictions of the single impurity Anderson model (SIAM). This analysis shows that the SIAM is not able to quantitatively describe, within a single set of parameters, the results of both spectroscopies. A considerably better agreement with experiments is instead obtained when changes in the hybridization parameter are allowed in the different final states. This result suggests that the hybridization between f and band states strongly depends on the 4f configuration as theoretically predicted.
