Comparative Study of Single and Double Ionization of Helium by Ion Impact
Abstract
We present three-dimensional angular distributions of the sum momentum vector of electrons emitted in double ionization in 6 MeV p + He collisions for fully determined kinematics. The results are directly compared to corresponding data for single ionization. Qualitative similarities between single and double ionization are observed. However, we demonstrate that based on these similarities it cannot be concluded that the collision dynamics underlying both processes are similar as well. Furthermore, we find that the projectile -- target nucleus interaction, which we found to be surprisingly important for single ionization earlier, is even more significant for double ionization.
