Ionization and electron capture cross sections for single and multiple electron removal from H2O by Li3+ impact

Abstract

SynopsisWe report experimental and theoretical ionization and single electron capture cross sections for single, double and triple electron removal from H2O by Li3+ with energies ranging from 0.75 to 5.8 MeV. Single electron removal is dominant for ionization, while double electron removal is dominant for electron capture. For the one- and two-electron removal cases, the calculations based on time-dependent orbital propagation in density functional theory show good agreement with experiment for the two collision channels studied.
