In this work, we study theoretically the single ionization of liquid water by energetic electrons by means of a first-order model obtained in the framework of an independent electron approximation and neglecting exchange effects. We compute double differential cross sections (DDCS) averaging over all molecule orientations and the solid angle of the scattered electron. Also, we obtain single differential cross sections by integrating the DDCS over all emitted electron angles. We compare with previous experiments and calculation for isolated water molecules as targets. Significant differences between gas and liquid phases are observed.
