Abstract
From the study of multielectron photoexcitations in atoms, a specific ansatz for the EXAFS atomic background is
derived, to improve or replace the conventional spline approximation. The elements of the ansatz describe multielectron
resonances, edges and shake-off features at proper theoretical energies. The approach is tested on the atomic background of Rb
ion and on EXAFS-free absorption spectra of rubidium vapor and krypton.
