Abstract
In low-energy noble gas ion scattering (LEIS) neutralisation plays an important role. Comparison of energy spectra of neutral scattered particles with ion spectra, and ion fractions derived from these data, provides information on neutralisation. To measure the energy of neutrals in the energy range (2-10 keV) a time-of-flight (TOF) spectrometer was used as well as a stripping cell in front of the electrostatic analyser. The results of both methods were compared for argon and neon neutrals of 5-10 keV with helium, nitrogen and argon as stripping gas. To investigate the properties of the cell neutral particles were used, obtained by scattering from a Cu(100) surface.Keywords
