Wave-Packet Convergent Close-Coupling Approach to Ion-Atom Collisions

Abstract

We extend the two-centre wave-packet convergent-close approach to proton scattering on excited states of hydrogen, collisions of bare ions (He2+ and C6+) with hydrogen, and proton collisions with the helium atom and He+ ion. The wave-packet approach is used to discretise the continuum of the involved atoms. The total cross sections for direct scattering, electron capture and ionisation, and the differential ionisation cross sections are calculated and compared with experimental data and other calculations, where available.
