【 摘 要 】

The fully differential cross section (FDCS) for single ionization p + He → p + e + He+at proton energy of 1 MeV is studied both experimentally and theoretically. The 3D angular electron distribution is presented. The role of electron-electron correlations both in a trial helium ground-state wave function and in the final helium state is inspected.
