✦ Synopsis

The mass spectra of cold ( 100 K), large (250 < n< 10000) aluminum clusters show 60 oscillatory features which seem to be associated with octahedral shells and subshells of atoms. The number of atoms in each oscillation is equal to the number of atoms needed to cover successively larger triangular faces on close-packed octahedra.

The ionization potentials ( IPs) of copper clusters (Cu,) up to 150 atoms have been bracketed using laser photoionization. Large decreases in IP at n = 2, 8, 20, 30, 34, 40 and 60 atoms are observed, as well as a strong odd-even alternation extending beyond 100 atoms. These features correspond to e
