Abstract

We report the observation of a polyatomic cluster constituent, fluorine in this case, recoiling from the projectile upon impact with a surface. The clusters (NaF)nNa+ (n = 1, 2, and 4), PF-6, BF-4, and SiF-5, with incident kinetic energies of 12-28 keV, were impacted on Au, SiO2, and α-cyano-4-hydroxycinnamic acid targets. The Au surface gave the highest F- yield when compared to the "light" SiO2 surface, for the same incident cluster. This supports previous MD predications of polyatomic cluster constituents "splashing" upon impact with a surface.
