On the Neutralization Models in LEIS
Three different neutralization models are discussed. In the continuum limit their connection is clarified for ion trajectories with unspecified time-dependence. The unifying model is fitted to experiment for He+ → MgO scattering. It is pointed out how difficulties, related to the use of relative ion fractions, can be circumvented. Therefore the results of DISC-experiments, which are absolute intensities, are compared with calculations on the basis of the Muda-Newns model.
