Surface Auger energy shifts in BCC transition metals

We calculate the Surface Auger Energy Shifts at the (110) surface of BCC transition metals. We use the equivalent core approximation, which reduces this problem to the computation of the Surface Segregation Energy of [ Z + 2] and [ Z + 1] impurities in a crystal of atomic number Z. The calculations...

Zusammenfassung:	We calculate the Surface Auger Energy Shifts at the (110) surface of BCC transition metals. We use the equivalent core approximation, which reduces this problem to the computation of the Surface Segregation Energy of [ Z + 2] and [ Z + 1] impurities in a crystal of atomic number Z. The calculations are carried out in the framework of the tight-binding approximation. General trends are derived and compared with those of single core hole surface binding energy shifts.
