Water molecule ionization by charged particles:<i>a short review</i>

Abstract

We present both singly differential and total cross sections for the direct ionization of water vapour by electrons as well as by ions (protons and alpha particles). An ab-initio calculation has been made by using the first Born approximation and an accurate molecular wave function proposed by Moccia [J. Chem. Phys. 40, 2186 (1964)]. The results of this model are compared to experimental data and to results obtained via semi-empirical models.
