Abstract :
The spectra of secondary ion emission in sputtering of GaAs monocrystal by molecular ions CuPc+, ¼CuPc+, CuPc2+ within the energy range Eo = 3-12 keV have been studied. The preferential yield of the cluster ions Ga+n with the number of the constituent atoms n more than 20 has been observed. This yield has increased significantly non-additively with the raise in the number of atoms in a molecular ion projectile.
