Target Ionization and Electron Loss Processes Induced by Neutral and Charged Hydrogen and Helium Projectiles in Water Molecule

Abstract

This work aims to present cross sections, for electron removal processesin neutral-atom collisions with water molecules, computed within the CDW-EIS(Continuum Distorted Wave-Eikonal Initial State) approximation. For describingthese reactions, two corrections are taken into account in the present model: the meanprojectile charge as a function of the impact energy and the dynamic projectile chargedepending on the momentum transfer during the interaction. The theoretical data, interms of the double differential and the total cross sections, for target ionization andprojectile electron loss processes is compared with existing data.
