Description
Summary:We have successfully observed linear dichroism in angle-resolved Yb3+ 3d... core-level photoemission spectra for YbB12 in cubic symmetry. Its anisotropic 4f charge distribution due to the crystal-field splitting is responsible for the linear dichroism, which has been verified by spectral simulations using ionic calculations with the full multiplet theory for a single-site Yb3+ ion in cubic symmetry. The observed linear dichroism as well as the polarization-dependent spectra in two different photoelectron directions for YbB12 are quantitatively reproduced by theoretical analysis for the ... ground state, indicating the ... ground-state symmetry for the Yb3+ ions mixed with the Yb2+ state.
