Popis: Secondary-ion mass spectra and energy distributions upon bombarding a gallium arsenide single crystal using Bim+(m = 1–5) cluster ions with energies of 2–12 keV are investigated. The gallium cluster ion yield grew nonadditively with the number of atoms in the cluster projectiles. A quasi-thermal component found in the energy spectra of secondary Ga+ and Ga2+ ions is indicative of the occurrence of the thermal spike mode upon cluster ion bombardment. The quasi-thermal component in the yield of atomic Ga+ ions upon bombardment with Bi2+–Bi5+–ions is 35–75%.
