title: Model of space- and energy-dependent electron flux density.
abstract: Analytic representation for the space- and energy-dependent electron flux density in terms of a phenomenological model was developed. The model was applied to electron energy degradation in gaseous argon. Flux density data were also generated from Monte Carlo simulations for 0.3-3.0 keV incident electrons. These data were used to determine adjustable parameters in our phenomenological model. From the nature of the cross section input to this model, we expect that the scaled flux density for most atomic and molecular gases will be similar to that obtained in this study.
