I have done such calculations (Slater's state) for the EELS spectra in Ni and 
Cu oxides - O K-edge and Cu and Ni L-edge. 
The result didn't satisfy me. The errors (relative 0.5eV for O K in the row of 
the CuO, Cu2O and NiO, absolute 20eV for 930eV of Cu L, 5eV for 530 of O K) 
are rather large, though some trends in changing are followed.
