Title: Monte Carlo simulation of range and energy deposition by electrons in gaseous and liquid water

Abstract

A stochastic simulation method employing suitable experimentally based cross sections has been developed for probing the spatial distribution of energy loss and the trajectory of 100eV to 1 MeV electrons in gaseous and liquid water. Elastic collisions and large-energy-loss inelastic collisions strongly influence the passage of electrons such that the separation between the initial and final (E = 25 eV) position is considerably smaller than the path length. At all energies, the mean axial and the mean radial penetrations are somewhat similar; however, the former is strongly influenced by inelastic collisions and the latter by elastic collisions. The effect of phase on the density-normalized range is small for energetic electrons, but differences are apparent at the lowest energies, < 2 KeV. The spatial distribution of energy deposition shows a marked dependence on electron energy. The spatial dependence of radial energy deposition and dose distributions in the axial and radial directions have been calculated. 52 refs., 11 figs., 3 tabs.
