Observation of Electronic Shells and Characteristic Products from Mass Abundance Spectra of Al Cluster and Al-C Cluster Anions

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 Al13-, Al23-, Al35-, and slightly, Al37- are local maxima, as predicted by the electronic jellium model. Mixed clusters AlnC- and AlnC2- are also shown, among which the most abundant species are Al3C2-, Al6C2-, Al7C- and Al7C2- in the small size range. The formation mechanism of these products is discussed.
