AUGER CROSS-RELAXATION ENERGY FOR METALLIC SODIUM, USING SCF CLUSTER MODEL CALCULATIONS

Self-consistent scattered wave calculations for a series of small sodium clusters are used to study the electronic relaxation involved in the creation of the double-hole final state in metallic core level Auger processes. The calculated extra-atomic cross-relaxation energy for Na(KL2, 3L2,3) transitions increases from Na4 to Na15 according to what one expects on the basis of physical insight. Although at most second neighbour interactions are involved in the Na15 cluster, its cross-relaxation energy already is in fairly good agreement with the corresponding metallic value. © 1979.
