## Description

- description: The electronic and crystal structures of YbCuxGa2-x were investigated
    by high-resolution X-ray absorption spectroscopy at the Yb-L3 absorption edge
    and X-ray diffraction under pressure. A rapid valence transition was found in
    YbCu0.5Ga1.5 around 5 GPa. For YbCuGa Nd YbCu1.5Ga0.5, the Yb valence increases
    gradually. Photoelectron spectroscopy was also performed around Yb 4d-4f resonance
    energy and at 8.4 eV.
