基于考虑电子-电子相互作用产生的原子多重态的杂质Anderson模型,研究了Ce化合物的三维和四维芯X射线光电子能谱。我们对三价Ce化合物CeF3、CeCl3和Ce2O3的3d和4d XPS进行了一致性分析,这是只有考虑原子多重态才能得到的。我们还将该方法应用于Ce-Ni化合物和CeO2混合价态Ce体系的光谱解释。我们发现,对多重态结构的分析给出了系统的多体电子态的信息。
The Ce 3 d and 4 d core X-ray photoemission spectra (3 d and 4 d XPS) of Ce compounds are studied based on the impurity Anderson model considering atomic multiplets arising from electron-electron interaction. We make a consistent analysis of 3 d and 4 d XPS of trivalent Ce compounds CeF 3 , CeCl 3 and Ce 2 O 3 , which can only be made by considering the atomic multiplets. We also apply the approach to the interpretation of the spectra of mixed valent Ce systems Ce–Ni compounds and CeO 2 . We show that the analysis of the multiplet structure gives information about many-body electronic states of the system.
