Using a laser vaporization/pulsed molecular beam cluster source, Al cluster anions and Al-C mixed cluster anions are produced and recorded by a time of flight mass spectrometer. Mass abundance spectra of the Al cluster anions in the size range from Al2 to Al42 show that Al-13, Al23, Al35, and slightly, Al37 are local maxima, as predicted by the electronic jellium model. Mixed clusters Aln C- and Aln C2 are also shown, among which the most abundant species are Al3 C2 , Al6 C2 , Al7 C- and Al7 C2 in the small size range. The formation mechanism of these products is discussed.
