Abstract: Aluminum oxide cluster anions with very broad mass range was produced on a home-made apparatus by laser ablation of α-Al_2O_2 in high vacuum. The recorded mass spectrum showes that, as n>5, only the series of the cluster anions with com-ponents of normal oxidation states were observed. Among the series of cluster anions, the anions foming a complete or near complete hexagonal close-packing structural unit have relative higher signal intensities.
