    and Density Functional Theory Calculations: Part IV. 4<i>f</i> Rare-earths'

## Description

- description: 'The valence band electronic structures of the elemental solids of
    4f rare-earths (REs: La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu)
    were studied by bulk-sensitive polarization-dependent hard X-ray photoemission
    spectroscopy (HAXPES).  Owing to the localized 4f electrons in REs, the valence
    band (VB) region showed complicated multiplet structures reflecting the 4f photoemission
    final states, except for La and Ce.  The profiles of the 4f multiplet structures
    did not depend on the X-ray polarization. In contrast, the VB spectra, which mainly
    consisted of the 5d and 6s states, near the Fermi-level (EF) weakly depended on
    the X-ray polarization.  The polarization-dependent VB spectra near EF for La
    and Lu were reproduced by the 5d and 6s partial densities of states, which were
    obtained from the density functional theory calculations for La and Lu, multiplied
    by photoionization cross-sections.  The complicated multiplet structures were
    also observed in the 3d and 4d core-level HAXPES spectra via the exchange interaction
    between the core-hole and 4f electrons.'
