Photoelectron spectra of AlnSm- cluster anions (0 ≤ n, m ≤ 10) were measured at photon energies of 3.49 and 4.66 eV, by using a magnetic bottle electron spectrometer. The AlnSm-. clusters were produced by laser vaporization of an aluminum-sulfur mixed rod in He carrier gas. The abundant AInSM clusters are three types of AlS-(Al2S3)k, AlS2-(Al2S3)k, and (Al2S3)k-, where an unit of Al2S3 aggregates with ion cores of AlS-, AlS2-, and Al2S3, respectively. Al3S3 is exceptionally stable with its geometrical structure.
