Analysis of core-level shifts in some metallic Ni compounds.

Lambrecht W.R.L.

The core-level shifts of NiSi2, NiAl, NiAl3 and NiCu with respect to pure metallic Ni and atomic Ni, including both initial- and final-state contributions, are calculated by means of linear muffin-tin orbital energy-band calculations, and their origin is critically discussed in terms of charge-transfer and configuration changes.
