✦ Synopsis

Intensity anomalies (magic numbers) have been observed in the mass spectra of sodium clusters containing up to 22000 atoms.

For small clusters (Na., n 6 1500) the anomalies appear to be due to the tilling of electronic shells. The mass spectra of larger clusters are well explained by the completion of icosahedral or cuboctahedral shells of atoms.

Mass spectra are reported for large sodium clusters warmed by a continuous laser beam prior to ionization. During the 1 ms warming period, the clusters lose more than IO% of their mass by single-atom evaporation. The resulting size distribution reveals what appears to be electronic shell structure f

The open-shell coupled-cluster method and the diagrams needed for its implementation are described. The method is applied to the electron ainities of Li and Na, which are calculated in two ways: as the ionization potential of the anions or as the energy of adding the second electron to the cations.

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
