Double- and single-electron-capture processes have been studied theoretically in the energy range from 50 eV to 2 keV by using a molecular-orbital expansion method. Atomic-type electron-translation factors have been implemented to ensure that the scattering boundary conditions are correct. The cross sections for single- and double-electron capture were found to cross each other at 500 eV, with double-electron capture being dominant at the lower energies studied. This finding is consistent with recent experimental measurements.
