The mean valence of Eu is determined by LIII-edge X-ray absorption (LIII-XA) and151Eu Mössbauer isomer shift measurementd for the mixed-valent compounds EuPd2Si2and EuNi2P2in the temperature range from 1.7 to 300 K. For EuPd2Si2, the behaviour of the satellite line observed in the Mössbauer spectra was investigated in detail. From a comparison of the LIII-Xa and Mössbauer results obtained on identical samples the valence/isomer shift calibration problem as well as possible final-state effects in LIII-XA spectra are discussed.
