Photoionization mass spectrometry experiments on cold and warm beams of AlN clusters reveal large, N-specific discontunuities in their cohesive and ionization properties. These can be interpreted in terms of bunching of electron levels - large-shell structure - through agreement with calculations based on the spherical-jellium approximation. Specific deviations found for intermediate-size ALN, and differences between aluminum and indium, are attributed to the perturbation by the ionic lattice of the spherical jellium orbitals.
