摘要: Collision of hyperthermal Cs+ ion beams with a Si(111) surface partially covered water gives rise to emission CsX+ cluster ions (X is atom or molecule) even when the monomer X+ are not produced. The yield for atomic and examined as function collision energy, based on which, we propose that species formed by recombination scattered, low kinetic energy gaseous neutral emanating from surface. It also demonstrated under this condition secondary flux contains large fraction molecular units.
