Abstract
Tin and gallium-tin clusters have been produced by 4 keV Ar+ ion bomba rdment of polycrystalline tin and the gallium-tin eutectic alloy and a nalyzed by time-of-flight mass spectrometry. The sputtered neutral spe cies were photoionized with 193 nm (6.4 eV) excimer laser light. Neutr al tin clusters containing up to 10 atoms and mixed gallium-tin cluste rs Ga-(n-m)Sn-m with n less than or equal to 4 for the neutrals and n less than or equal to 3 for the sputtered ionic species have been dete cted. The measured distributions of mixed clusters with equal nucleari ty have been found to be nonstatistical most likely due to significant differences in the ionization efficiencies of clusters with equal nuc learity but different tin content.
