Notes:
Using a comprehensive set of electron cross sections, we have carried out a Monte Carlo study of the spatial and energetic aspects of electron degradation in the energy range from 30 eV to 1 MeV. The results are given in terms of a four-dimensional spatial yield spectral distribution. This is represented by a simple approximate analytic form which is convenient to use for calculating the spatial distribution of the initial species created due to electron energy degradation. We also investigate the sensitivity of these electron transport results to some of the input cross sections. We have specifically examined the influence of the assumed form of cross sections for vibrational states on the gross yields. We conclude that in transport calculations it is important to use approximate forms with reasonable asymptotic limits. Finally, we call attention to molecular processes which are important in microdosimetry but whose cross sections are particularly uncertain.
