Abstract Neutral aluminum clusters have been produced by laser vaporization technique, ionized by a low-power near-threshold laser light and detected using standard TOF spectrometric methods. Ionization potentials have been deduced in the low size range. In the large size range 250〈N〈1400 the patterns of the mass spectra exhibit a regular and continuous oscillation, originating from size-dependent ionization threshold effects. The period, constant on a Ne 1/3 scale (Ne=3N is the number of valence electrons), is approximately two times shorter than the one observed in alkali experiments. This feature is analyzed in terms of shell structure.
