Calculation of total cross sections for ionization and charge transfer in collisions of multicharged ions with water molecules

Abstract

Classical (CTMC) calculations of single electron capture and single ionization cross sections are carried out for collisions of H+ and C6+ collisions with H2O molecules in the impact energy range 25<E<5000 keV/amu. The calculation employs a multi‐center model potential for the interaction of the active electron with the H2O+ core. The results agree with the experimental data when the independent electron event model is applied to evaluate total electron capture and ionization probabilities from the corresponding one‐electron ones.
