CDW-EIS theoretical calculations of projectile deflection for single ionization in highly charged ion-atom collisions

We present continuum distorted wave-eikonal initial state (CDW-EIS) theoretical calculations for the projectile deflection in single ionization of helium by heavy-ion impact as a function of ionized electron energies. These calculations account for the helium passive electron shielding in the intern...
