The effect of electron correlations on the Auger spectra from the substitutionally disordered narrow-band metal alloys with partially filled bands is studied within the degenerate Hubbard model. Perturbation theory is used limited to the second order in U/w (U Coulomb integral, w bandwidth) for the calculation of the one-particle Green function, and the ladder approximation for the two-particle Green function. The effect of disorder is included within the single-site approximation. The theory is illustrated on a simple model of the copper-nickel alloy.

X-irradiation at 77 K of a NaCl:Fe++ crystal produces orthorhombic and axial Fe+ ESR spectra of comparable intensities. The corresponding Fe+ (ortho) and Fe+ (tetra) centers are identified with, respectively, a substitutional Fe+ perturbed by a nearest and a next nearest cation vacancy. At 170 K the cation vacancy of Fe+ (ortho) jumps to the next nearest neighbour position enhancing the Fe+ (tetra) intensity. Above 215 K the vacancy moves away completely and the unperturbed Fe+ (cubic) is formed. It is concluded from this study that before X-irradiation Fe++ perturbed by either nearest or next nearest cation vacancies occur in roughly comparable amounts and that the activation energy for cation vacancy motion in NaCl is 0.72 eV. Irradiation aux rayons X a 77 K d'un crystal NaCl:Fe++ produit des spectres de RPE Fe+ pos-sedant des symetries orthorhombiques et axials. Les centres Fe+ (ortho) et Fe+ (tetra) correspondants sont identifies avec un ion Fe+ substitutionel perturbe, respectivement par une lacune cation voisine ou prochaine voisine. A 170 K la lacune cation de Fe+ (ortho) saute vers la position prochaine voisine et augmente ainsi l'intensite de Fe+ (tetra). Vers 215 K la lacune se separe completement et le centre Fe+ (cubic) non perturbe se forme. On conclut qu'avant l'irradiation les deux types de centres Fe++ perturbes sont presents avec des concentrations comparables et que l'energie d'activation pour le mouvement d'une lacune cation dans le NaCl est de 0,72 eV.

It is found that the simple formula , where A = 328, B = 9.3118, and a = 1/x the nearest-neighbour distance in Bohr radii, is a very good fit for the detailed variation of the F-centre peak absorption energy, E (in Ryd), with a, for the 16 alkali halides with NaCl structure, excluding CsF. The first term arises from incoherent photon scattering leading to electronic level transitions. The second term is a diffraction term, arising from the coherent scattering of photons from relaxed ionic aggregates around F-centers separated on the average by distances of the order of optical wavelengths.
