Low-energy ion scattering from an Ag(110) surface covered by molecular adsorbed oxygen

Molecular oxygen adsorbed on an Ag(110) surface has been studied by compute r simulation of low energy ion scattering. The lying-down adsorptions of mo lecular oxygen with an orientation of its molecular axis along the [110] az imuth on an Ag(110) surface were been simulated. The energy distributions a nd the behaviour of the scattering loops of scattered He+. N+ and Ne+ ions have been presented. It was shown that the behaviour of the scattering loop s gives the possibility to determine the location of adsorbed molecules on the surface. The development of the proposed technique would allow an estim ate of its feasibilities. (C) 1999 Elsevier Science B.V. All rights reserve d.
