Abstract
A kinematically complete experiment for double ionization of He by 3.6 Mev/u Au53+ impact has been performed using a high-resolution integrated multi-electron recoil-ion momentum spectrometer. Nine out of twelve momentum components of the outgoing fragments were measured. The electrons sum-momentumis found to be in the forward direction and the recoil ion almost compensates the electrons being ejected into the backward hemisphere. The momentum change of the projectile is found to be small compared to the momenta of the ejected reaction products, which reveals similarity with photoionization. The strongest interaction among the collision partners is found to exist between the recoil ion and the electrons.
