Abstract
The He\({^+}\)–He collisions are treated with a three-electron atomic-orbital close-coupling method at intermediate energies. The cross sections are shown for single-electron capture, target excitation, projectile excitation, and target ionization. The results are overall in good agreement with experimental data and previous theoretical results. The minima in the cross sections for target excitation to \(2{^1}S\) and \(2{^1}P\) around 20 keV/u are also discussed.
