摘要：

A pronounced satellite structure in the 2p absorption spectrum of Ti02 is reported, which is attributed to final states in which the local excitation on the metal is screened by polarization of the valence electrons on the ligands. By comparing the X-ray absorption spectrum with the photoemission spectrum we can determine the influence of the excited electron on the screening of the core hole potential. © 1990 The Japan Society of Applied Physics.
