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