Abstract
In an earlier paper [Radiat. Res. 92, 1 (1982)], a bipartition model of electron transport has been proposed. In this model an electron beam is divided into two components: one describing the penetration of the small-angle scattered electrons, another describing the diffusion of electrons that have undergone large-angle scattering. In the present work, which consists of a series of three articles (the third to appear at a later date), the bipartition model of electron transport is refined and is applied to problems that include electron transport in inhomogeneous media and discrete energy-loss processes. In the present paper (the first one in the series), the treatment is restricted to the application of the continuous-slowing-down approximation model to homogeneous media and to comparisons of the results with Spencer's moment method and with experimental data. The comparisons show that the improved and more flexible bipartition model has high precision.
