摘要：

The Haydock recursion scheme is for the first time applied to the matrix inversion required for calculations of x-ray absorption cross sections. A mapping of the multiple-scattering contributions into continued fraction coefficients which appears to improve the convergence of the multiple-scattering series is derived. Numerical applications to three different systems-Mn ion in water solution, a copper-imidazole molecule, and c-Si-are presented.
