Multiple differential cross sections for the ionization of liquid water molecules by fast electron impact

Abstract

We present a theoretical study of single ionization of water molecules in liquid phase by impact of fast electron in a coplanar geometry. Multiple differential cross sections are computed through a first order model in a framework of an independent electron approximation. For the first time in this kind of study, the wavefunctions for a single water molecule in liquid phase are computed in a realistic way through a Wannier orbital formalism. A comparison with previous theoretical and experimental results, the latter corresponding to the gas phase, shows a good agreement. The main physical features of the reaction (such as binary and recoil peaks) are also observed in our results.
