Abstract
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.
