最近，我们研究了K壳层光电子卫星/主线分支比在CO的高分辨率光电子能谱和零电子动能（ZEKE）谱的阈值行为。电子飞行时间测量是在斯坦福大学同步辐射实验室用球形光栅单色仪进行的。高于Cls和Ols电离阈值的ZEKE谱表明，相似的1 s-{sup 1}{pi}- {sup 1}{pi}伴态在激振能量和强度分布上存在显著差异.将提出八个Cls卫星态的分支比的能量依赖性。在305 eV附近的三重态耦合Cls-{sup 1}{pi}-{sup 1}{pi}卫星区域中，我们能够分辨出三个分量，它们显示出分支比随光子能量的变化。
We have recently studied the threshold behavior of the K-shell photoelectron satellite/main line branching ratios in CO with high-resolution photoelectron spectroscopy and zero electron kinetic energy (ZEKE) spectroscopy. The electron time-of-flight measurements were performed at the Stanford Synchrotron Radiation Laboratory with a spherical grating monochromator. The ZEKE spectra above the Cls and Ols ionization thresholds show remarkable differences in the shake-up energy and intensity distribution of similar 1s-{sup 1}{pi}- {sup 1}{pi} satellite states. The energy dependency of the branching ratios of eight Cls satellite states will be presented. In the region of the triplet coupled Cls-{sup 1}{pi}-{sup 1}{pi} satellite around 305 eV, we were able to resolve three components that show a variation in the branching ratios as a function of the photon energy.
