Abstract

The Eu LIII-edge X-ray-absorption spectrum of EuPd2P2 exhibits a double-peaked white-line structure typical for mixed-valent materials, while Mössbauer isomer-shift and other magnetic measurements prove the divalent ground state of this compound. This discrepancy clearly shows the possible presence of final-state configuration-interaction effects in the LIII-edge spectra of heavy-rare-earth systems, as well as a significant 4f covalent bonding, contrary to previous assumptions.
