| 摘 要： | 为进一步研究饰的配合物在双烯烃催化聚合反应体系中的作用,我们用XPS研究了一些铈的化合物,为探讨饰配合物的电子结构积累必要数据.对于某些简单的饰化合物,已有一些作者研究1,2,3]对于Ce3d的伴峰指定是Shake-up过程4],还是Shake-down伴峰5,6,7]说法不一我们通过系统研究,对于Ce3d区域的峰提出一些看法。

| Abstract: | A study of the core-electron x-ray photoelectron spectra showed the presence of satellite structure for the 3d and 4d signals in Ce_2O_3, CeO_2, CeCl_3, CeF_3. These satellites are discussed in terms of coexcitation of the charge transfer type principally O2p to Ce4f transitions. It is confirmed that in the cerium compounds studied the satellites are due to energy-loss (representing shake-up) rather than energy-gain (shake-down) processes. |
