In this thesis, we have investigated experimentally the scattering of hydrogen atoms and ions on solid surfaces at grazing incidence. The projectile energy ranges from several hundred eV to few keV. The formation of H- ions is studied on highly oriented pyrolytic graphite (HOPG) surface; and surface diffraction is carried out on LiF(001) surface with H° and H+ particle scattering. Both experiments were performed in the same experimental setup (see Figure 1.2 and 2.1)—with grazing scattering geometry and a PSD (position sensitive detector) located downstream to record scattered particles. For charge state analysis a set of electrostatic plates is inserted between sample and PSD. During the experiment, coincident measurement technique is used...
