we show that the inclusion of modern recoil ion momentum spectroscopic methods [1] allows one to directly illustrate the phenomenon of interest. As an example, we use 183 keV/u collisions of C6+ on Na. The energy was chosen simply so that electrons ionized with the same speed as the projectile vp have an energy of 100 eV. A similar study has been conducted by Sulik et al. who employed 150 keV/u C+ + Xe using conventional techniques [2]. As shown in the latter work, the interpretation of multiple collisions of the ionized electron between nuclear centers relies on a combined experimental theoretical interpretation. We point out that the use of recoil ion momentum spectroscopy makes the observation of the collisional dynamics directly observable. For the sample system, we have employed the CTMC technique using a Hartree-Fock model potential for the Na(3s) outer shell electron. The CTMC is a complete three-body method that provides the momentum components of all particles after the collision [3]. From the momenta, we simply restrict observation to only those events that proceed with a longitudinal momentum loss of the projectile collision.6+ on Na.
