(e,3e) on helium at low impact energy: the strongly correlated three-electron continuum
Double ionization of the helium atom by slow electron impact (E0=106 eV) is studied in a kinematically complete experiment. Because of a low excess energy Eexc=27 eV above the double ionization threshold, a strongly correlated three-electron continuum is realized. This is demonstrated by measuring and calculating the fully differential cross sections for equal energy sharing of the final-state electrons. While the electron emission is dominated by a strong Coulomb repulsion, also signatures...[Show more]
