Abstract

Absolute triply differential (e, 2e) cross section measurements are presented for He at incident energies E₀ = 32.6, 44.6, 64.6, and 104.6 eV with equal energy sharing and the θ₁₂ = π configuration. Results of distorted partial-wave calculations agree with the measurements; those of convergent close-coupling calculations agree with the relative angular distributions, and with absolute values after rescaling by consideration of the singly differential cross section.
