Abstract
Collision strengths have been calculated for electron-impact transitions between the O2+ ground configuration terms 3P, 1D and 1S for energies up to 0.5 Ryd above excitation thresholds. Configuration-interaction wavefunctions are used for the target states. These functions give accurate oscillator strengths for all transitions of the type 2s22p2-2s2p3. The method used to obtain collision strengths for the (e+O2+) system is also used to calculate the positions of bound states for O+. The calculated positions of the near-threshold resonance states are in satisfactory agreement with positions predicted from iso-electronic sequence extrapolations. The results are compared with those obtained by Ormonde et al. (1973).Keywords
