Abstract: Using a laser vaporization/pulsed molecular beam cluster source, AI cluster anions and A1-C mixed cluster anions are produced and recorded by a time of flight mass spectrometer. Mass abundance spectra of the AI cluster anions in the size range from AI-2 to AI-42 show that AI-13, AI-23, AI-35, and slightly, AI-37 are local maxima, as predicted by the electronic jellium model. Mixed cluster AInC- and AInC-2 are also shown, among which the most abundant species are AI3C-2, AI6C-2,AI7C- and AI7C-2in the small size range. The formation mechanism of these products is discussed.
