| 英文摘要 | Double ionization of the helium atom by slow electron impact (e-0=106 ev) is studied in a kinematically complete experiment. because of a low excess energy e-exc=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 of more complex dynamics of the full four-body system are identified. |
