Close-coupling calculations are carried out for the [ital Q] values for electron capture processes in collisions of multiply charged ions with atoms over a broad range of energies. For single-capture processes the results for N[sup 7+]+He and O[sup 8+]+He collisions are in good agreement with the experimental data of Wu [ital et] [ital al]. [preceding paper, Phys. Rev. A 50, 502 (1994)]. To compare with the experimental [ital Q] values for the transfer ionization (TI) and the true double-capture (TDC) processes, an independent-electron model was used to calculate double-electron-capture cross sections. By combining with the calculated average fluorescence yields, the theoretical [ital Q] values for TI and TDC processes are also found to be in fair agreement with the experimental data. We also compared the [ital Q] values calculated by the close-coupling method and by the classical-trajectory Monte Carlo method.
