Abstract
The Hubbard model is applied to icosahedral, face-centered cubic (FCC), hex agonal close-packed (HCP), and body-centered cubic (BCC) clusters having N = 13 atoms. Exact ground-state results are given as a function of the Coulo mb repulsion strength U/t, number of electrons nu; and total spin S. Electr on correlation effects on magnetic behavior and structural changes are disc ussed.
