摘要:

给出了CeRu $_6$ $_4$ Sn的Ce3PDMATHABMM芯能级的体敏硬X射线光电子能谱学数据。使用全多重态和配置迭代模型的组合,我们能够获得准确的线形分析的数据,从而考虑到强等离子体激元强度的相关性。我们得出结论,CeRu $_4$ Sn $_6$是一个适度的混合价化合物的重量为8%的Ce $f^0$配置在基态。

英文摘要:

Bulk sensitive hard x-ray photoelectron spectroscopy data of the Ce 3$p$ core level of CeRu$_4$Sn$_6$ are presented. Using a combination of full multiplet and configuration iteration model we were able to obtain an accurate lineshape analysis of the data, thereby taking into account correlations for the strong plasmon intensities. We conclude that CeRu$_4$Sn$_6$ is a moderately mixed valence compound with a weight of 8% for the Ce $f^0$ configuration in the ground state.
