摘要：

Exact-diagonalization calculations have been performed to study the electronic structure of d band metal surfaces, with specific applications to a Ni(001) surface. Results of local-density-approximation band-structure calculations are taken as the starting point. A realistic surface model of d electrons has been constructed in a tight-binding scheme, with the strong short-range d-d correlation fully taken into account in a periodic small-cluster approach. Calculated results show some interesting features induced by many-body effects. The implications and consequences of the results are discussed.
