Abstract :
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.
