基于简化杂质安德森模型并结合斯莱特积分和自旋轨道相互作用描述的相互作用，讨论了价态混合对 CeRh/sub 3/ 和 CeO/sub 2/ 的 Ce 4d X 射线吸收光谱中多重态结构的影响。 CeO/sub 2/ 在阈值前区域中的光谱与金属 Ce 化合物的光谱的显着偏差的解释与其 3d 核心能级光谱的解释一致。
The effect of valence mixing on multiplet structure in the Ce 4d x-ray absorption spectra for CeRh/sub 3/ and CeO/sub 2/ is duscussed on the basis of a simplified impurity Anderson model combined with the interactions described by the Slater integrals and the spin-orbit interactions. A remarkable deviation of the spectrum for CeO/sub 2/ in a prethreshold region from that for metallic Ce compounds is explained consistently with an interpretation for their 3d core level spectra.
