Space-dependent aspects of electron degradation.
Space- and energy-dependent flux densities were computed by a Monte Carlo method of electron degradation for 0.1-3.0 keV incident electrons in argon. These flux densities contain the basic information about the electron degradation process and can be used to calculate a yield for any inelastic state at any spatial position. Numerical results were analytically represented in terms of the recently introduced phenomenological model. It was found that flux densities multiplied by an absorption cross section in argon are approximately the same as flux densities multiplied by an absorption cross section in nitrogen. This feature provides a basis to use an analytical approximation of flux densities from this study for any gas.
