Abstract

We have performed a kinematically complete experiment for the transfer ionization reaction 0.15-1.4 MeV p+He-->H⁰+He²⁺+e^- by measuring the three-dimensional momentum vector of the He²⁺ ion in coincidence with the scattering angle and the plane of the H⁰. In the measured fourfold differential cross section we can clearly distinguish between the independent two-step process of capture plus ionization and the correlated e- e Thomas scattering. We find a v^-7.4+/-1P scaling for the total cross section of the e- e Thomas process.
