“…The successive columns correspond to increasing values of Q. In the FDCS given by the FBA, for equal energy emission, the main features have been thoroughly described in an earlier paper [56]. In the contour-plot representation, the momentum-transfer direction is fixed.…”

“…These structures are usually denoted as the binary and the recoil peaks, for which the electrons' momenta are located along the dashed lines drawn in each plot of Fig. 3 [56] axially symmetric in relation to the Q direction. In the binary emission, the total electronic momentum is similar to the momentum transfer k 1 + k 2 ≈ Q, and the recoil ion is mainly a spectator during the collision (R ≈ 0).…”

In this work, we present a second-order Born series treatment for the double ionization of He by ion impact. In particular, we show that the well-known independent events and independent electron models naturally result from an on-shell treatment for the second-order Born approximation. A transition amplitude which coherently includes first-and second-order terms in the projectile interaction is introduced to study the role of the two-step-1, shake-off, and two-step-2 mechanisms at different impact energies. Fully differential cross sections for proton and antiproton impact are presented and analyzed for different projectile momentum transfers.
