The role of the wave packet coherence on the ionization cross section of He by p+ and C6+ projectiles

We study the role of the projectile coherence in collision processes. We analyze in particular
the ionization of He by p+ and C 6+ projectiles at 1 and 100 MeV/amu, respectively. We
compare the influence of this effect in both cases by performing a First Born calculation
convoluted with a gaussian distribution, which accounts for the initial incoherence of the
projectile wave packet. Even though this is the simplest approach that one could implement
to solve this problem, it gives good agreement with the experimental results.
