## Photoionization, X-ray emission and UV excitation energies are calculated for SiOa by the SCF Xcc method and the transition-state procedure. In all cases agreement between calculation and experiment is good. The SiOz-cluster is found to be adequntc for describing localized excitations in quartz

โฆ Synopsis
X-ray absorption spectra of Si, SiO and SiOt in the Si K edge region are presented. They reveal a strong influence of the type of silicon bond on the structure of the absorption spectra situated towards high energies of the edge. These spectra show that the SiO oxide cannot be taken as a mixture of Si and SiOz.
