ABSTRACT
As energetic electrons pass through matter they lose energy primarily through collisions with bound electrons. Ionization cross sections for all primary and secondary electrons are needed to follow the history of an incident particle and its products, covering all ranges of energy transferred in individual collisions. Cross section data for liquid water are scarce, as measurements are either impractical or very dif‚cult (see Section III). In this section we describe the KURBUC code system, which uses water vapor cross sections, differential, total, and partial cross sections for ionization.
