Energy and charge distributions of fast nitrogen ions reflected from metal surface at grazing incidence

摘要

Energy and charge distributions of ions scattered under grazing incidence conditions from metallic surfaces are studied theoretically. The energy distribution of scattered ions with fixed charge is calculated by the energy distribution of reflected ions with equilibrium charge and charge fraction of these ions. The charge fractions of scattered ions are estimated by charge exchange cross sections. We calculated the energy and charge distributions of 1 MeV nitrogen ion scattered from platinum surface. The calculation results are in qualitative agreement with experimental data.
