Close-coupling approach to electron-impact ionization of helium

Abstract
The close-coupling theory of electron-impact ionization of helium is studied. It is found that the "raw" convergent close-coupling equal-energy-sharing amplitudes converge to half the required amplitudes. As in the e-H case, solving the close-coupling equations yields amplitudes that behave as results of a finite Fourier expansion of a step function. We argue that the close-coupling formalism readily solves the e-He ionization problem with equal-energy outgoing electrons at all practical incident energies, and demonstrate it at the most difficult kinematic case of 2 eV above threshold.
