A Generalized Sturmian Treatment of (e, 3e) Processes Described as a Three-Body Coulomb Problem

The double ionization of helium by high energy electron impact is investigated. The pure four-body Coulomb problem may be reduced to a three-body one in accordance with the use of the first Born approximation. Even within this frame, major unexplained discrepancies subsist between several theoretica...
