Total and State-Selective Charge Transfer in He2+ + H Collisions

Journal Article · · Journal of Physics B: Atomic, Molecular and Optical Physics

Total and state-selective cross sections for charge transfer in {approx}1-1000 keV/u He{sup 2+} + H collisions have been calculated using a variety of theoretical approaches, namely, the classical trajectory Monte Carlo, atomic-orbital close-coupling and lattice, time-dependent Schroedinger equation methods. Comparison of the results with available experimental measurements and other theoretical cross sections indicates the regimes in which each method is most reliable. The present cross sections here, and their evaluation in light of existing data, provide a new benchmark for this inelastic channel in the fundamental collision system He{sup 2+} + H over a wide range of collision energies and final quantum levels.
