Abstract—The shape of the x-ray K absorption spectrum of sulfur in the normal spinel CdIn₂S₄ is calculated
using the FEFF7 program. Local densities of free electron states of S, Cd, and In are calculated in the theory of
multiple scattering in the local coherent potential approximation. A comparison of the obtained results with the
experimental x-ray SK spectrum demonstrates good agreement between them. © 2000 MAIK “Nauka/Interpe-
