[en] It is of importance to determine the region that is probed by the photoelectron of an X-ray absorption experiment. It is shown that this region depends on the photoeletron kinetic energy through its effective mean-free path. To assert these ideas ab-initio calculations are applied to semiconducting and insulatings compounds
