摘要：

The electronic shell structure of small monovalent metal clusters has been studied in the free-electron model and in the Huckel model. The discretized free-electron Hamiltonian is shown to be equivalent to the Huckel Hamiltonian. Consequently the two models yield similar shell structures for the low-lying energy levels. The level structure depends on the shape of the cluster but not on the lattice structure of the Huckel model.
