Detailed investigations of two-center collision dynamics

The combination of recoil ion and ionized electron momentum spectroscopy provides an unparalleled method to investigate the details of ion-atom collision dynamics. In order to predict scattering behavior and collaborate with experimental projects, the classical trajectory 3- and n-body Monte Carlo method has been modified to yield complete momenta information for ionized electron spectra in the collision plane defined by the incident projectile and outgoing projectile or recoil ion. To illuminate the richness of these spectra, calculations of 300 and 500 keV p and p- single ionization collisions with He are presented for low q/v perturbation strengths. For strong q/v collisions, the 100, 300 and 500 keV/u Ne10+ on He systems are illustrated. Strong asymmetry of the slow and saddle point electrons are predicted for antiproton and highly-charged Ne10+ projectiles. Furthermore, The electron capture to the continuum spectra for Ne10+ are observed to have not only the expected asymmetry in the longitudinal direction, but also a strong asymmetry in the collision plane.
