摘要
Antiproton-impact single ionization cross sections are calculated for both H-2(+) and H-2. A one-active-electron time-dependent close-coupling method is used to calculate cross sections for H-2(+) at various molecular orientations for incident energies ranging from 1.0 to 200.0 keV. The results are compared with other theoretical results. Both one-active-electron and two-active-electron time-dependent close-coupling methods are used to calculate cross sections for H-2 at various molecular orientations for incident energies ranging from 10.0 to 50.0 keV. Differences between the calculations for H-2 are attributed to strong electron correlation effects. The results are compared with experimental and other theoretical results.
