We report a combined experimental and theoretical study of the electron-impact ionization of water (H₂O) at the relatively low incident energy of E₀=81eV in which either the 1b₁ or 3a₁ orbitals are ionized leading to the stable H₂O cation. The experimental data were measured by using a reaction microscope, which can cover nearly the entire 4π solid angle for the secondary electron emission over a range of ejection energies. We present experimental data for the scattering angles of 6⁰ and 10⁰ for the faster of the two outgoing electrons as a function …
