A Complete Postversion of the Three-Body Continuum Distorted Wave-Eikonal Initial State Approximation for Single Ionization of Multielectron Atoms
Single electron ionization of helium targets produced by the impact of
fast proton beams is investigated. The postversion of the continuum distorted wave-eikonal
initial state into a three-body approximation is reformulated, including the
dynamic screening produced by the nonionized electron. This dynamic screening is
shown to play a main role in the determination of double differential cross-sections. A
good agreement is found with predictions obtained employing the prior version of the
model, so that post-prior discrepancies are almost eliminated.
