Abstract

The influence of strong electron correlation effects on polarized CuL₃ x-ray absorption spectra has been studied using an extended p-d-model and the approximation of an instantaneous perturbation. The structure of vacant one-electron Cus and Cud states beyond the threshold is modelled using a self-consistent field method for the X_α-scattered waves. The calculations are in good agreement with experimental data for La_2-xSr_xCuO₄ and YBa₂Cu₃O_7-δ.
