Abstract: Both positive and negative aluminum cluster ions were generated by laser ablation of AIN sample. Their mass distributions were analyzed using a time-of-flight mass spectrometer. The magic numbers are 7, 14 and 23 for cluster cations, and 13, 23, 63 for anions. They all agree very well with spherical jellium model.

Key words: Aluminum cluster, Laser abalation, Spherical jellium model
