Abstract

In this work we study theoretically the single ionization of liquid water by impact of energetic electrons. A realistic description of the wavefunction for an isolated water molecule in the liquid phase is made by means of a Wannier orbital formalism. We develop a first order model within the framework of an independent electron approximation in which the relaxation of the target is not taken into account. The double differential cross sections are computed and compared with experimental data and theoretical calculations for gas phase.
