Classical/quantum correspondence in state selective charge transfer and ionization cross-sections for Li q+ ( q=1–3) ions with neutral hydrogen

Abstract

Classical trajectory Monte Carlo method is used to study the charge transfer and ionization cross-sections of fully and partially stripped ions of lithium with neutral hydrogen atom at energies region 30–200 keV/amu. At the same energy range, only charge transfer cross-sections are calculated in the framework of boundary corrected continuum intermediate state approximation. In both these methods, the interaction of the active electron in the target with incoming projectile ions is taken by a suitable potential containing both a long-range part and a short-range part. Variation of total captures cross-sections with impact energy compare favorably with the available experimental observations and other theoretical findings. In addition, sub-shell distributions of total capture cross-sections are given in graphical form.
