Low energy He+ ion scattering (LEIS) studies have been performed on TiO2(110), polycrystalline Ti, and Ti with oxide and water overlayers. It is found that the energy dependence of the O/Ti LEIS intensity ratio for TiO2 is due to ion neutralization and/or reionization and is not the result of shadowing effects. The studies of water covered surfaces indicate attenuation of LEIS intensities due to the presence of hydrogen atoms.
