摘要: We report fully differential cross sections (FDCS) for the single ionization of helium by a 75 keV incident energy proton. Previous three-body distorted wave (3DW) calculations this collision system are in poor agreement with absolute magnitude experimental measurements. The 3DW approximation treats four-body problem as an effective which passive electron does not participate collision. have developed full approach participates It will be shown that FDCS is very sensitive to treatment electron-ejected interaction. Results our compared recent
