A Bipartition Model with Single-Scattering Approximation for the Calculations of Reflection of Energetic Ions from Surfaces

A bipartition model for ion transport in solids has been presented. Unlike the earlier bipartition model, a single-scattering approximation has been adopted and angular correlation of energy transfer has been partly taken into account. By the present bipartition model, the reflection coefficients and energy spectrum of reflected ions have been calculated. The results show that the present bipartition model gives better descriptions of reflection although it is simpler in calculation than the earlier bipartition model.
