报道了EuPd_2Si_2样品的穆斯堡尔效应和LIII吸收光谱实验。在0.51个电子的热致原子价变化范围内，对这两个原子价灵敏光谱进行了定量关联。由此产生的关系between151 Eu异构体位移和LIII确定的价是用来提供一个试探性的估计的价态的一些其他1：2：2 Eu化合物，并强调在何种程度上磁秩序和价混合共存于这样的化合物。
Detailed Mössbauer effect and LIIIabsorption spectroscopy experiments on a sample of EuPd2Si2are reported. A quantitative correlation of these two valence sensitive spectroscopies is made over the range of the thermally induced valence change of 0.51 electrons. The resulting relation between151Eu isomer shift and LIIIdetermined valence is used to provide a tentative estimate of the valence states of a number of other 1:2:2 Eu compounds and to emphasize the extent to which magnetic order and valence mixing coexists in such compounds.
