We have measured for the first time full sets of coplanar (e,3e) angular distributions for double ionization of He, at an impact energy of  ∼  5 and  ∼  1 keV. Ejected electrons are detected with equal energies, 10 and 4 eV. Comparison is made with analog (γ,2e) results, and deviations from the dipolar limit are pointed out. The data are also compared with two calculations, using either a four-body final-state wavefunction for the three electrons moving in the field of He²⁺, or the convergent close coupling method.
