## Description

- description: Electronic structure of the intermediate valence systems Yb3Si5 and
    Yb3Ge5 were investigated by using high resolution x-ray absorption spectroscopy,
    resonant x-ray emission spectroscopy, and photoelectron spectroscopy. XAS and
    RXES revealed that the Yb valence in Yb3Si5 decreased monotonically with decreasing
    temperature. In contrast, in Yb3Ge5, it remained nearly divalent and exhibits
    little temperature dependence. The experimental valence-band spectra were further
    compared with the density of states calculations performed using the local density
    approximation plus dynamical mean-field theory (LDA+DMFT).
