Abstract

We show that the strongly correlated 4 f-orbital symmetry of the ground state is revealed by linear dichroism in corelevel photoemission spectra, as we have discovered for YbRh2Si2 and YbCu2Si2. Theoretical analysis shows us that the linear dichroism reflects the anisotropic charge distributions resulting from a crystalline electric field. We have successfully determined the ground-state 4 f symmetry for both compounds from the polarization-dependent angleresolved core-level spectra at a temperature well below the first excitation energy. The excited-state symmetry is also probed by temperature dependence of the linear dichroism where the high measurement temperatures are on the order of the crystal-field-splitting energies.
