Calculation of ionization of H2O by H+ with classical and semiclassical methods

Abstract

Total and singly differential (in the electron energy) cross section of electron emission in proton collisions with H2O are obtained at energies in the range 10 keV to 5 MeV. Two non-perturbative methods are employed, one classical and one semiclassical, both combining a multi-center target electron potential and an independent particle statistics. Excellent agreement with experimental results is found. © Published under licence by IOP Publishing Ltd.
