Research Abstract

We conclude that the non-local processes is the screening of core hole with the electrons surrounding atoms around the hole of an absorbed atom. We measure X-ray absorption spectra and emission spectra around the Cu-K edge. We found the olarization dependence and valence dependence of the non-local process. Moreover, we found the same process in the region of soft X-rays.
