摘要: Abstract Double ionisation is considered within the context of impact parameter version continuum distorted wave eikonal initial state approximation. Starting from independent event model, correlation ejected electrons accounted for by explicitly including Coulomb density states factor electron–electron interaction in calculation. Total cross sections proton, alpha particle and Li 3+ on helium, proton lithium, over energy range 50–2000 keV/amu are presented. It concluded that inclusion exit channel crucial if an adequate account double process to be obtained.
