Abstract: Binary cluster ions consisted of aluminum and sulfur(Al_nS_m~+, n up to 63, m up to 94) are produced by laser ablation of a mixture of aluminum powder and sulfur powder. It was found that the formed cluster ions have a uniform increment of Al_2 S_3 in the composition. The photodissociation of the mass-selected cluster ions also show a simple dissociation channel by loss of(Al_2S_3)_x (x=1 or 3). The structural features of the cluster ions have been discussed.

Key words: Atomic cluster, Photolysis, Structural stability, Laser ablation
