    Notes: Abstract Absolute doubly differential cross sections for electron emission occurring in fast (0.5 MeV/amu) H0 — and He0 — He collisions have been measured using standard non-coincidence techniques as well as emitted electron — charge state analysed projectile coincidence techniques. The comparison of these data with results obtained for H+ and He+ impact provides insight into the influence of one or two loosely bound projectile electrons on the probabilities for projectile, target, and simultaneous projectile — target ionization. PWBA calculations for these systems demonstrate good agreement with the experimental data for target and projectile ionization and indicate the importance of including simultaneous ionization processes in the theoretical treatment.

    Equilibrium convoy electron production and charge exchange (1989)
    Springer
    The European physical journal 13 (1989), S. 45-49

    Notes: Abstract Based on the results from measurements of equilibrium convoy electron yieldsY e (q) in coincidence with projectiles of different outgoing chargesq from Pb31+ (1.4 MeV/u) and C6+ (1 MeV/u) on carbon foils we present a simple rate equation for convoy electron production which gives a consistent interpretation of yields, for light and heavy projectile ions in nonequilibrium and equilibrium of charge exchange. It will be pointed out that from convoy electron yields in the equilibrium regime of charge exchange the relative importance of ELC and ECC processes to the total yield cannot be determined. However, absolute normalized equilibrium convoy electron yieldsY f (q) allows us to estimate the overall contribution of convoy electrons to charge exchange in dependence on the ionization stateq.
