Strong directional out-of-plane scattering in multiple ionizing highly charged ion-atom collisions

摘要

The azimuthal ((phi)(sub r)) and polar angle ((theta)(sub r)) scattering of projectiles in coincidence with recoil ions has been studied for 0.53 MeV/u Fe(sup 8+) + Ne. For high degree of ionization of the target we find the resultant transverse momentum of all electrons emitted into the continuum to increase with the number of ejected electrons and to have a direction mostly not co-planar with the scattering plane.
