Electron impact on atmospheric gases, 3. Spatial yield spectra for N2

Spatial yield spectra have been calculated for electron energy degradation into molecular nitrogen gas using a Monte Carlo method for 0.1‐ to 5.0‐keV incident electrons. These spectra contain the spatial yield information about the electron degradation process and can be employed to calculate a ‘yield’ for any inelastic state at any position in the medium. Because of the spectrum's useful nature and simple characteristics, the three‐variable spatial yield spectrum U(E, z, E0) is analytically represented as well. This analytic form can then be easily applied to atmospheric and laboratory problems dealing with energetic electron degradation.
