"Molecular projectile effects for kinetic electron emission from carbon- and metal-surfaces bombarded by slow hydrogen ions";
Nuclear Instruments & Methods in Physics Research Section B,
Total yields for kinetic electron emission (KE) have been determined for impact of hydrogen monomer-, dimer- and
trimer-ions (impact energy <10 keV) on atomically clean surfaces of carbon-.ber inforced graphite used as .rst-wall
armour in magnetic fusion devices. The data are compared with KE yields for impact of same projectile ions on
atomically clean highly oriented pyrolytic graphite and polycrystalline gold. We discuss KE yields for the di.erent
targets if bombarded by equally fast molecular and atomic ions in view to ``projectile molecular e.ects’’ (di.erent yields
per proton for equally fast atomic and molecular ions), which are expected from calculated electronic projectile energy
losses in these target materials.
