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