摘要：

We report numerical calculations of the spectral-weight functions for the lattice Anderson model on small clusters of square and tetrahedral geometry by exact diagonalization. Parameters in the weak-hybridization-strong-interaction sector are considered. The behavior of the f levels is studied as the occupancy varies from the doubly occupied limit to the nearly empty case.
