Ionization and electron capture in ion-molecule collisions: Classical (CTMC) and semiclassical calculations

Total cross-sections for electron capture and electron production in proton collisions with N2, CO and H2O, are evaluated using a classical trajectory Monte Carlo treatment for collision energies between 30 and 3000keV. A semiclassical close-coupling treatment has been also employed for proton colli...

Description
Summary:Total cross-sections for electron capture and electron production in proton collisions with N2, CO and H2O, are evaluated using a classical trajectory Monte Carlo treatment for collision energies between 30 and 3000keV. A semiclassical close-coupling treatment has been also employed for proton collisions with H2O, to discuss the accuracy of the CTMC treatment. Singly differential cross-sections for electron production have been also evaluated. Total and differential cross are compared with experimental data. ► Evaluation of cross-sections required for ion tracks simulation. ► Implementation of the CTMC method for ion-molecule collisions. ► CTMC cross-sections show very good agreement with the experimental results. ► Close coupling calculations support the validity of the CTMC treatment
