Corrections due to multiple scattering are considered and it is shown how they may be either suppressed by Lorentzian energy averages if they involve long scattering paths or included via renormalization factors if they arise from shadowing effects.

,Str?mende Bewegung der Gase und D?mpfe,d solids has increased the pressure on theorists to provide accurate cross section calculations for atoms in a variety of local environments. The quantity of most direct experimental interest for these studies is the absorption coefficient, μ(ω). A typical calculation [1] proceeds by evaluation of Golden Rule matrix elements.

Using the sudden approximation we made a ΔSCF calculation for both one- and two-electron excitations of the L-edges. The result shows that the calculation at least qualitatively explains the multielectron excitations past the L-edges.

In this talk we focus on the measurement of absorption spectra for heavy atoms (principally copper) in low-symmetry environments. Our motivation is to understand how metallo-proteins “do their thing.” Before getting to specific model systems, we discuss some of the theoretical problems in general.

The normal electronic configuration of the rare-earth (RE) ions in the trivalent state may be written as (Xe) 4f., with n = 0, 1,...14 for La., Ce.... Lu. respectively.
