Secondary ion emission from vapor-deposited water ice has been investigated in exploring the influence of phase transitions on the desorption yield of H2O ions, particularly, the hydronium H3O+ and the cluster ions (H2O)nH3O+. For 1.5 MeV N2+ ion bom

Au nanoislet targets (∅ 2–60 nm) were bombarded by 200 keV polyatomic ions (40 keV/atom), which deposit their energy mainly in the nuclear stopping mode: ∑(dE/dx)n = 30 keV/nm and ∑(dE/dx)e = 2 keV/nm. The matter desorbed in the form of nanoc

The interaction of 72 keV Au 400 ions (with a diameter of approximately 2 nm) with nanodispersed gold targets has been studied. These interactions are dominated by elastic collisions. The gold nanodispersed target with 2–12 nm nanoislets was bombar
