Abstract
We develop an analytic representation for the spatial (radial and longitudinal) yield spectra in terms of a model containing three simple "microplumes." We apply the model to electron energy degradation in molecular nitrogen gas for 0.1 to 5 KeV incident electrons. From the nature of the cross section input to this model it is expected that the scaled spatial yield spectra for other gases will be quite similar. The model indicates that each excitation, ionization, etc. plume should have its individual spatial and energy dependence. Extensions of the model and aeronomical and radiological applications of our model are discussed.This publication has 9 references indexed in Scilit:
