Single Electron Capture

Applying a real-space, real-time implementation of time-dependent density functional theory coupled to molecular dynamics (TDDFT-MD) non-adiabatically, we study the ionization and fragmentation of water dimer in collision with a proton at 250 eV. Four different incident orientations with various impact parameters are employed to account for orientation effects. The reaction channels, electronic density evolution, scattering pattern and energy loss of proton are obtained. We find that proton is scattered away for all impact parameters and the head-on collision effects the energy loss of proton dominantly as well as the scattering angle. The locations of peaks of the scattering angles are similar to those corresponding to the energy loss. The single-electron capture, the double-electron capture as well as the total electron capture cross-sections are obtained. We find that the single-electron capture cross-section contributes most to the total electron capture cross-section and the calculated total electron capture cross-section is in reasonable agreement with experimental and other theoretical results with respect to water gas and liquid water.

Capture Cross Sections

Absolute total cross sections for single-electron-capture are measured for [Formula: see text] and N+ ions traversing N2 molecular gas of collision energies in the range of 0.60 to 1.5 keV. These cross sections are found to be in the range of 3.97 - 6.25 Å2 for [Formula: see text] ions, and in the range of 0.46 - 1.67 Å2 for N+ ions. A comparison is made between the present measurements of the total cross sections of the N+ + N2 system and all the experimental results, which are represented by B. G. Lindsay et al.,1 for the O+ + N2 system. The present measurements of the total cross section of the N+ + N2 system are in partial agreement with measurements of B. G. Lindsay et al.,1 and in an excellent agreement with the measurements of Moran et al.,2 The present measurements of the total cross sections of the [Formula: see text] system are compared to the theoretical calculations and the experimental results of the same system.23 The results are in disagreement with each other.
